Why are ULTRA FOAM Walkalong Gliders so Different?

- Ultra Foam is only a few times more dense than air itself, so walkalong gliders made from it fly VERY slowly.

I am a sculptor and i use 1 lb EPS and sometimes 2 lb EPS foam. I have an actual hill of scrap and have started to draw gliders planning to make a variety of them. Gotta put all this scrap to good use! We typically don’t sculpt any blocks smaller than 12 inches thick, and the slabs of 4, 6, 8 inch thick ‘mattress’ get used for padding when shipping large sculptures. But even still, I have way way more than I can ever use. I have a CNC Hotwire cutting table and can cut vector files of wing profiles, started drawing some glider parts in Adobe illustrator my nephew is turning 5 next weekend and I think I will bring several experimental gliders to his birthday party in a park.
these are so much fun, simple and yet fun filled, thanks for sharing
Great to see another one of your videos, always fascinating and educational 😍👍
Thanks Grandad, I love your eclectic project videos!

Hi Slater. Good to see that you are still thinking and doing. Drf
Thanks Daryl. I think we're both slowing down in the frequency of video uploads. But your work with the pop pops and your family's European canal trip will be relevant even in hundreds of years. If anybody has trouble finding the canal boat video, it's here czcams.com/video/hLYZHUPexbw/video.html
I loved it! Great video
Hey, You sold some of these to Billy Vaughn, the Hang Gliding Manager. I have yours in my hand. LOL! I just saw your website and figured it out! I might buy some.
Merry Christmas!
As soon as my dad finishes work I am telling him to get me this
Me too
Hard to believe how slow they fly!
Can someone explain to me how it works, how it flies when you hold the cardboard in your hand
Essentially a walkalong glider is a very slow (so it has to be very lightweight) glider that stays up because the air it is in is rising. Walking with a board scoops up air it encounters. You learn to keep the glider where the air is being deflected up by the board. Thie following video at about 11.20 compares it to "ridge-lift" that allows hang gliders and soaring birds to stay in the air for hours

Where can I buy that Ultra Foam??? I live in Taiwan.
Hi SerikD. We send lots of foam sheets and gliders to schools in Taiwan. Try this link for gliders. If you just want plain foam sheets to experiment with, contact me.
Which paper do you use?
I use foam paper: thin sliced foam. Some is heavier and some is lighter. The lighter kind is harder to find.
brilliant!
Cool RC videos on your channel, Ahmad.
lol thanks. Your tutorials on building rubber band powered planes was a very large part of my childhood. Also the plastic bag sky lanterns were pretty awesome as well (along with a bunch of other cool things).
@@amk1108 Thanks Ahmad, that sort of feedback is a great encouragement to keep developing new projects. My latest obsession is an easy-to-make boomerang.
Ahh those things are soo simple, but tricky to master
Slater you just keep pushing the envelope in walk along!
Thanks Bill. I like your recent rocket/glider video!
The rocket gliders are rather fun, I have a swing wing one to try yet.
The narrator sounds like the narrator from a Kitty Hawk Kites hang gliding training film by David Harris. I think he's Canadian and it was made in the 80's. Anyone know more?
This is all I could find czcams.com/video/masxpjAjVU8/video.html
@@sciencetoymaker Thats's funny. It's 3 miles from my house and I taught there for 8 years. I shot some of that footage of the lessons. Do you know who is narrating it though? Is it you narrating? I've made these and Terry Sweeney gave me his design that I made a hot wire cutter and produced a few from the pink foam.
@@316woodworks9 I did not narrate it; don't know who. You mentioned Terry Sweeney. He was one of the first people to help me get started with the gliders. You can see him at about 1:20 in this video

@@316woodworks9 Terry and the MacCready family used Extruded Polystyrene (XPS) which is the smoother foam insulation sold in building supply (usually blue or pink) used underground for basements. Also in grocery packaging for meats and vegetables and in take-out containers. I've gone to Expanded Polystyrene (EPS) which is the white, beady stuff you see on cups, cheap insulation, electronics packaging etc. because it is considerably lower density so it flies slower. There is a cost, however. EPS is flimsier than XPS so my designs have a fatter aspect ratio and I have to be really careful handling them.
@@sciencetoymaker That's correct. The plans I emailed you are from Terry and I did make them out of the pink foam. Pretty durable but your EPS concept is pretty insane. It's so light that it works best with that thin gauge wire. I'm definitely getting back into this again and want to get my son's school interested.
Wow
1:29 That’s a static cling problems
How did you get this foam
As the video shows, from packaging.
We’re did you buy it from?

i like it i also made one 👍👍👍
Làm sao mua một xốp tàu lượn? Tôi ở Việt Nam.
Nó có thể được tìm thấy ở những nơi sản xuất. Nó được sử dụng để đóng gói. It might be found where there is manufacturing. It is used for packaging.
👍💜🧡💚

IT'S SO STUPID
Wha ya mean?
