Diet Coke and Mentos… In Zero Gravity… only on MAKE!


Robert writes-

This last weekend the whole family flew on Space Adventure’s G-Force One (just featured last night on Mythbusters). Being science nuts, we spent some time thinking up experiments to do in microgravity, and ended up testing the Diet Coke & Mentos reaction.

We hacked a camera port and mount into a portable glove bag (to contain the mess) and filmed the whole thing with the Casio EX-F1 at 300 frames a second, using light from an emergency exit window. The results were a bit equivocal (“more research is needed, hahahah!”) but the video is interesting, as is the story of how the experiment evolved and how we managed to do it. for the whole story. for just the video.

We also hacked a hard drive into a gyroscope and flew it, but I won’t have the video of that for a few weeks.

Kudos to the Space Adventures people, btw. They went the extra mile to help us work out a way to do the experiment (they are extremely science-friendly) and coordinated with the TSA to ensure that there would be no last minute hiccups.

    Been there, done that, got the t-shirt.

    Seriously though, that was pretty cool. I suspect the effects of natural gravity assist the violence of the reaction, because the microgravity version was surprisingly tame compared to other “menticulation” reactions I have seen.

    (hmm, preview doesn’t show the link – I hope submit lets it through)

    You can see the T-shirt I referred to at

    I did an experiment with glass marbles in zero gravity a year ago.
