Water balloons IN SPAAAAAACE!!

I’ve always found it fascinating watching slow motion videos of water balloons.

Isn’t that cool? Because the water has to overcome inertia, inertia is proportional to mass, and water has a reasonably high density, it takes a moment for the water to realise it’s falling. Of course, it’s barely a split second of actual time, but in slow motion it’s pretty amazing to watch.

So when I discovered this video (made by Don Pettit on board the ISS) of bursting water balloons in zero gravity, I thought it was absolutely incredible.

Interesting too, how water in zero gravity behaves much like the molten wax in a lava lamp…
