Ski Chair - Unsafe at any speed

Papa-G writes -
My son found an abandoned wheelchair in the summer and after spending a week having chariot races (i.e. tying ropes to a bike and getting pulled too fast) it ended up in my garage until winter.
As you can see from the image, I have no room for anything in the garage, so I told him - find something to do with that or I’m throwing it out.
A trip to Goodwill and $5 later, we had skis attached to the chair.
Because of the high centre of gravity, this chair feels very unstable, couple that with the complete lack of steering/braking and you’re ready for fun on the slopes!

HOW TO - “Fly” a human powered hydrofoil - the “Aquaskipper”

Tim shows you how those Aquaskippers work and how to take one out for a spin…
The “Aquaskipper” is a human powered hydrofoil made by Inventist.com . It’s similar to the original Swedish Trampofoil, which is no longer available. There’s also one called the “Pumpabike” from South Africa.
They’re also called “hull-less watercraft” and “flapping wing propulsion vessels”. You bounce up and down to make the wing fly and propel you. If you stop you fall into the water and swim back to the dock. It’s completely ridiculous and works really well once you get the hang of it. It’s hard to do at first but that seems to make it even more fun.

instructables : “Collaboration”

We have about 500 projects and 500 members of the MAKE group on Instructables, and now there’s another great way to do projects together with the new “Collaboration” feature… Eric writes - “Today, we’ve launched the incredible new feature, collaboration! Enable other users or groups to help you work on your Instructables. Made a mistake? Don’t worry, there’s also now versioning, so you can rollback to an earlier version of your Instructable.” - Link.
Excellent work Eric and crew! Makers, go check it out!
