Very well done instructional video. If only all "how to" videos were this clear. Thanks Slater.

[@sciencetoymaker]

Thanks Daryl.

THE RETURN!!!!!!!!!!!!!!

Great idea and video.

[@ProfessorPonko]

I loved it! Great video

I have made a mosquito hang glider with thin paper and it worked

[@GroovyDominoes]

wow someone should try putting a tiny camera on the board

[@texasjacksonswf]

It's air moving under the wing/airfoil creating high pressure and over the wing creating low pressure otherwise known as lift. When air merges behind the wing it rolls downward and off the wingtips, creating vortices. This downwash in aviation is called "ground effect". Search wingtip vortices. They're fascinating to see.

[@sciencetoymaker]

Yes, my understanding is that when the air is redirected downward from the wing, a force must have acted on it; and for that action the opposite reaction (Newton's Third Law) is lift of the wing. And I think "ground effect" is when the vortices that you referred to are interrupted by the ground--very low flying. When flying higher off the board, we create rising air akin to "ridge lift" that gliders, hang gliders and soaring birds gain altitude in. Ridge lift is like flying in thermals in that both are rising air. But ridge lift differs from thermal lift in that the later is caused by hot air rising and the former is caused by wind striking hills/mountains and being diverted upward to some extent.

It worked well and I am happy playing with it

[@Kanekighoull]

What material is your glider made up of? Is it paper?

[@mayerly3817]

Un poco de todo

[@anneryedits1700]

Whats the name of the paper

[@Cat_with-threatening-aura]

0:32 the guys face 😂

[@Kanekighoull]

I made a walk along glider using 80gsm paper. It's the follow foil and I cannot fly it. Any different material I can use to build the glider?

[@sciencetoymaker]

John Collins, Phil Rossoni and others have made fixed-wing walkalong gliders from paper. But no matter how brilliant their designs, the fact remains that paper--even very thin paper--is many times heavier than thin foam for a given surface area. So they glide much faster and I find them to be difficult to adjust. Thin EPS foam, on the hand, can be only a few times more dense than air itself. You can see more about foam gliders here. goo.gl/Y25oyJ It is possible to slice your own foam if you cannot buy it. There are also spinning paper gliders that are known as "tumblewings" or "tumbling wings". They fly slower, although they can be tricky to launch.

[@Kanekighoull]

@@sciencetoymaker thank you so much sir, for the detailed explanation. Is it possible to make any kind of walk along glider using butter paper or origami instead?

[@yuriugisa6943]

I cant belive in my eyes

[@ktg1012]

Me too. I just made a gideo of me flying a mosquito glider

[@ktg1012]

At first, when i started flying gliders, i just couldn't believe that there is some wave of air deflected of the board keeping the glider levitated

[@simpsonli8579]

How to make the airplane don't fall?

[@sciencetoymaker]

The board deflects the air up, so it lifts the glider.

[@sujathavk8280]

One question.... how thin should the foam be

[@sciencetoymaker]

Thickness depends on several factors. I have used sheets anywhere from 0.5mm to 1mm. Experiment.

[@thanakrit25]

Can you show me how to make it. Thank you.

[@sciencetoymaker]

You can learn more here sciencetoymaker.org/walkalong-glider-airsurf-air-surfing/ Also, there are people in Thailand already making and flying walkalong gliders. Perhaps you can connect with them. kzbin.info/www/bejne/rXeoYpSdereArqcsi=_Sj7NU_081kIUA8A

[@zd29]

Hi I have a problem with my follow foil. I used tin foil to make a paper airplane and cardboard to fly my plane but it did not work.

[@sciencetoymaker]

When you call it "follow foil" am I correct in assuming that you are making a John Collins (The Paper Airplane Guy) design? It is possible to make walkalong gliders out of paper, but it's many times heavier than 1/2mm thick EPS foam, which is what you see people flying in this video. Making it out of aluminum foil is an interesting idea, but do that experimenting AFTER you get a paper one flying. And it's difficult to find good paper now. Phone book paper was excellent--about half the weight for a given surface area than printer paper. See if you can find an elderly person with an old phone book stored away somewhere. Most news paper seems to be somewhat lighter than printer paper. Here's what I suggest: start with one of the spinning walkalong glider designs. John Collins invented the "tumbling wing", also called the "tumblewing". I have a design called the "big mouth tumblewing" and another called "dihedral magnus effect glider". I also sell the ready to fly foam gliders at my website

[@hubbyflashgaming5700]

Where can you buy this paper

[@sciencetoymaker]

I make and sell the EPS foam sheets, but it is expensive to mail outside the U.S. You can cut your own foam sciencetoymaker.org/walkalong-glider-airsurf-air-surfing/make-your-own-gliders/hotwire-cut/

Thank you !

[@multirole8233]

the board is round

[@user-bs3vh4cp9s]

What pepper is it?

[@ktg1012]

It isn't paper, it is just thin half millimeter EPS foam cut with a hot wire cutter. Paper is too heavy to fly on a wave of air. It will not catch it

[@ligaconjastica6872]

Bell pepper

can you make?

[@sciencetoymaker]

Yes, but the gliders are made from .7mm EPS foam, not paper. sciencetoymaker.org/walkalong-glider-airsurf-air-surfing/

[@markjohnsean8091]

sir can you make a tutorial with paper?

[@sciencetoymaker]

I can not make this kind of glider out of paper. Paper is much heavier and not strong enough. There is a spinning kind of glider that can be made from paper: various designs of tumblewing. This is one kind kzbin.info/www/bejne/l52cdoWqZrWcfLs They are more difficult to launch and fly, but paper is everywhere.

[@cryptimation3991]

kzbin.info/www/bejne/n5m6lmOopdRosJo here is one

[@shaikmohammedabdullah5219]

how to gain speed?

[@sciencetoymaker]

First, heavier gliders tend to fly faster. Then, where they are relative to the board can also make them go fast. If the glider is closer to the front edge of the board, then more updraft tends to hit the back of the glider, so it tilts down a little, going faster. It takes a lot of practice.

[@shaikmohammedabdullah5219]

Can you tell me more? What did you make the glider from? These gliders are made from EPS foam that is less than 1mm thick.
