Non-Newtonian fluids are liquids that are also sort of solid but also sort of neither but also sort of both? They’re very thick liquids or very giving solids, depending on what you want to call it. That’s why they’re so fun to do science experiments with. The Backyard Scientist went and filled up balloons with…

Inflatable furniture isn’t a new idea. College dorms are filled with blow-up sofas and air-filled mattresses. But none of them look like designer Seungjin Yang’s inflatable pieces, which are created using the same balloons a birthday party clown relies on to entertain screaming children.

When we last checked in on Project Loon—Google’s moonshot project to blanket the world with internet-packing weather balloons—one had just circumnavigated the globe in a very quick 22 days. I just attended a talk at Google I/O and got some more info about the challenges the team faces in making this wild-ass project…

A water balloon fight is no fun when kids have to keep running back to their parents to tie the balloons for them. Using tiny elastics the Bunch O Balloons came up with a slightly better way to automatically tie 37 water balloons at once, but these Zorbz appear to have the best solution yet, automatically sealing…

Every person who has seen the movie Up and also enjoys dreaming about fanciful things every now and again has thought about flying away in balloons like Carl Fredricksen. Professional daredevil and crazy person Erik Roner just did it. He bought tanks of helium to pump up giant balloons to make him fly.

If you think about it, ball pits are gross cesspools that hide violent bits of static charges and virulent diseases that smell like melting plastic. They are not fun.
