|
| In addition to being able to glide very far, you could launch it
| with a meter stick.

| friend and I were messing around and added a dumb amount of
| weight to the front of one. Think it was a clip his mom used to
| dry cloths outside. Nearly doubled the weight and put the
| center of balance way near the front of the plane. We expected
| a nosedive. Gave it a toss and it 3x'd the flight length
| easily. It was already fairly decent and you could easily get
| across a room with little changes. Now it was easily getting
| across his yard.

| What a great feeling that must have been.
|
| It's funny, it's kind of similar to walkie talkie transmissions
| in the summer. They can get tunneled through the troposphere
| and suddenly you are talking to people you never expected to
| contact.
|
| A couple summers ago I was out in my yard, called out randomly
| on my little 5W handheld, and the signal went just over 8 miles
| through flat, forested city neighborhoods into the back end of
| a guy's directional antenna on his house. We had a good laugh
| at that. I've run tests in the neighborhood and I'm usually
| lucky to get out a single mile.
|
| During the same season I also like that I can pick up Indian
| music from an FM radio station 150+ miles south of me (KSJO),
| using a small pocket radio. Searching around for those signals
| is also kind of like fishing.
|
| Anyway. I think it's pretty neat how different seasonal
| conditions change the dynamics of a hobby interest or a
| science.

|
| Just for info: these use the "Letter paper", not A4, as I
| remember. But most designs should work anyway.
|
| "The most used of this series is the size A4, which is 210 mm x
| 297 mm (8.27 in x 11.7 in) and thus almost exactly 1/16 square
| metre (0.0625 m2; 96.8752 sq in) in area. For comparison, the
| letter paper size commonly used in North America (8+1/2 in x 11
| in, 216 mm x 279 mm) is about 6 mm (0.24 in) wider and 18 mm
| (0.71 in) shorter than A4. Then, the size of A5 paper is half of
| A4, as 148 mm x 210 mm (5.8 in x 8.3 in)."

| Nice.
|
| However, I see that it doesn't have the plane which I usually
| made as a child.
|
| As an aside, I was a wannabe pilot who never went to flight
| school. I love aircrafts, and I love long haul flights (I never
| got tired from the multiple 15+ hour India<->America flights I
| took).
|
| In India to become a pilot you had to learn math and physics in
| high-school, and at my highschool, you could either take Math-
| Physics-Chemistry-Biology, or Math-Physics-Chemistry-
| ComputerScience.
|
| Computer Science (CS) meant they taught you coding, Boolean
| algebra (incl. Karnaugh Maps), history of CS and the internet,
| and we eventually moved onto OOP.
|
| I'm terrible at Biology, so I choose the latter option. I found I
| liked CS, and now here I am :)
|
| Though I never went to flight school, even today I'm still
| passionate about it. I follow these youtubers -- Mentour Pilot,
| Captain Joe, Kelsey (74gear), and Dutch Pilot Girl.
|
| And I closely follow the aircraft models and the industry in
| general. I can tell what model an aircraft is just by looking at
| it.
|
| I sometimes have those _what if_ moments.
|
| It's like the great American poet Robert Frost's _The Road Not
| Taken_ , except I took the well travelled road.

|
| Nice to watch if you have a tiny one that you launch from a
| great height.

| I think USA is a better place for these kinds of activities,

| My interest in science started when a friend and I folded a few

| structured experimentation you could design things that actually
| got better with each generation. Where would the improvements
| stop?
|
| With hindsight, I realise that most of the improvements we
| measured were really just statistical noise. We never had a
| control plane, so if one by accident flew better one test, then
| we would tweak something and then we would naturally see
| regression to the mean, but we would record that as a tweak that
| made things worse.
|
| To little me it was a lesson in deliberate design. To grown-up me
| I guess it's a lesson in how easy it is to delude yourself
| without proper experiment design and statistics.
|
| Anyway, then after seeing my interest my father brought me an
| early Windows program that contained animated instructions on
| some paper plane designs. One of them was vastly superior to
| anything I had ever seen. But with the years, I forgot how to
| fold it. I had been looking for it for over 20 years when a few
| months ago, I wanted to show my son (of two years) a good paper
| plane and guess what? I think I've found the design! But it took

| In fourth grade we had a paper airplane contest, but they had a
| restriction on the design: a circle about the size of a quarter
| was on the page, and no fold or crease could go through the
| circle.
|
| The circle was located a few inches above the exact center of the
| paper.
|
| Anyway I made a "dart", and just offset the angle a little to
| avoid the circle. It was good, and most of the competition was
| incredibly bad. And a few maybe had a bad launch. One throw only.
|
| One clever design was submitted by a duo composed of my two worst
| nine year old enemies: Derek and Derek's sidekick. It was
| basically a UFO (saucer) made by carefully crumpling the edge
| until it was a nice size to throw. They threw it sidearm with one
| finger hooked around the rim.
|
| It really sailed, maybe went twice as far as the second best
| plane: my plane.
|
| But their plane was disqualified on the grounds that it wasn't a
| plane. So, I was deemed winner.
|
| For the announcements the next morning, my name was announced as
| the wrong-gendered version (something like Jesse announced as

|
| Since there was no rule against it, we've allowed it. Some of

| yreg wrote:
| Haha. It wasn't my game and it was called "The Stick".
|
| Played outdoor, between two teams who face each other on
| the opposite sides of a small playing field. In the middle
| there is a stick stuck into the ground.
|
| The players are assigned various numbers. In each round a
| moderator announces a predicate such as "even numbers" or
| "factors of three primes" or "sum of digits is a power of
| two" etc.
|
| The players who satisfy the predicate are allowed onto the
| field and their goal is to get the stick and bring it to
| their side. If a player mistakenly steps into the field
| they are out of the game. Grabbing and pulling other
| players while battling for the stick is fine.
|
| The last time this was played it rained a bit and the
| terrain was muddy and slippery and also the game was
| probably needlessly violent. Too many people didn't enjoy
| it and we've decided to retire it.
|
| ----
|
| While I'm at it, the third most controversial game was a
| game where teams had to complete various tasks in and
| around the village after the sunset, find some objects,
| etc. We always have at least one such game and it is
| usually one of a kind, played just that one time.
|
| This time there was a special twist. Unknown to the rest of
| the players, each team had a traitor whose goal was to
| hinder the progress of their team as much as possible. The
| traitor whose team finished in the last place was the
| actual winner of the game.
|
| The activity was not scored, but the players were led to
| believe it is going to be scored.
|
| When we played it some teams had conflicts and it sowed a
| lot of distrust and paranoia that spilled into the next
| day's games as well. Also the players who gave the game a
| lot of effort were angry that it is not scored in the end.
| It was the opposite of a team building activity so we never
| explored it further.
|
| Although I have to say, I'm still intrigued by the concept
| and would like to try it in some other form one day again.

| My friends and I could never get any of the pointy darts to work

| https://www.instructables.com/The-Hammer-Paper-Airplane/
|
| Carefully made, it flies straight when yeeted without trimming,
| and the blunt nose handles landings without damage. I surmise

| high-speed performance by preventing the trailing edge from
| fluttering. Could this also be why the world record designs tend

|
| A design that's amusing to experiment with is the most
| minimalistic glider, made with a heavy roll-fold of the leading
| edge of the paper and three parallel folds forming the wings and
| fuselage.[1] The parameters being length & number of folds and
| camber of the wings, it can be tuned to manage a hard throw
| straight before stalling and leveling out to a long flight in
| phugoid motion.
|
| Flying rings are interesting, too. The rotationally symmetrical
| type formed from only a roll fold and tape (purity
| notwithstanding) are similarly minimalistic

| Out of all paper planes I tried, it has the best flying
| capabilities by far.
|
| Form and function really come together in this one. It looks
| beautifully simple and elegant. And that's also how it flies.
| When you throw it from a rooftop, you are in for quite a show. It
| often flies loooong smooth circles. If you are lucky with the
| wind, it can stay in the air quite a while.
|
| I do not use A4 paper though. I prefer A5, which is half the size
| of A4. I usually tear an A4 into two equal halves and use one of
| them.
|
| I also do not do the crease at 04:18. Without it, the paper plane
| is even more beautiful, because you can put it on a flat surface
| and it stands on its own.

| Wow, after the first two folds, this plane really folds itself.
|
| The first fold is at 22.5 degrees, which makes all further
| folds have alignment with the base of the plane.
|
| My entire life i was folding a plane that starts with two
| classic 45 degrees, then a 90 degree fold of the top 2/5th of
| the paper, again 45 degrees tip, hook in the little triangle.
| Fold over symmetry line and add wings however you want them.
| It's quite similar with hooking in the tip (the 04:18 crease),
| but not nearly as elegant to fold. It is capable of doing a
| looping, and is otherwise a decent flyer.
|
| Curious about yours though, can't try it out here as I'm in the
| office.

| Yes, it's cool how logical all the creases are. The first two

| The Nakamura Lock, a schoolyard classic worldwide. It has a

| The only source I can find is a Reddit comment stating that the
| design is named after Nakamura for having invented the type of
| fold that holds the plane together (https://redd.it/j2yjsd)

| Let me guess how this works: from the nose view, the paper
| strips being at one side cause the stick to angle toward it,
| since the center of mass is close to the stick than the center
| of the drag force due to the stick's relatively small cross
| section for its mass. This causes the craft to keep pitching
| up. In addition, the same difference in cross sections between
| the hoops and the the stick from the plan view give it roll
| stability. Meanwhile, the larger hoop being at the back causes
| more drag, giving it yaw stability.
