Some things are inherently outdoor activities. Also, I really want to try this.

No, I would definitely call that an explosion, as it ended up all over the room.

Small watermelon. But it's a reference point, and as a philosopher once said, "knowing is half the battle".

I keep wondering about the extensional semantics in his theory of knowledge though.

Any chance of a video of people stacking straw on a camel's back?

Can someone please tell me how much time elapsed? Just because if someone maybe wanted to do this as an experiment for an after school science club and needed to budget time? (And bribe the Chief Custodian...)

Also, the center is obviously the most fragile point, but had they set aside 1/3 of the bands to cover the watermelon at the thirds of its large radius (i.e. 1/6, 1/3, 1/6), they would have likely breached skin before.

The way they're doing things the watermelon explodes because it finally overcomes the structural integrity in the line between the vertices, but with extra rubber bands they would have both increased pressure between the extra thirds and the vertices and between the center band cluster and the extra thirds.

Awesome.

Next up: How many rubber bands, made into a rubber band ball, does it take to make a black hole? (Note: This should be researched not only outside, but outside the solar system.)

I'm a little surprised they didn't wear some kind of eye protection. I wouldn't want a watermelon seed exploded into my eyeball.

The Slo Mo Guys have a high speed video camera and their own YouTube channel. Here is their version of the stunt, which has an excellent slow motion moment-of-explosion.

I can't be the only one mortally afraid of rubber bands snapping and injuring you.

peagood: now I want to join your after-school science club!

What kind of protective eyewear would a school require for rubber-banding a watermelon? and what other fruits & veggies --- tomatoes? grapefruit? --- would make fun messes?!?

Although I am not a scientist, I enjoy watching science in action and sometimes think, "I could also do that science."

This is so stupid, I posted it to my facebook page.

I like how when they started it was none rubber band at a time. The they started doing them in bunches. I also like how they went 1074, 2074, 3074, etc. I find that funny for some reason.

Also, don't watch the follow up video with the Yorkie. Totally disappointing that it could only take 2073 rubber bands.

easily confused:

I don't know, but I've just spent time creating a file for it and will now move on to planning whatever fundraiser I'll also have to run to afford having syntaxfree come and teach it too. I'm imagining two teams, and a race to see which watermelon explodes first...kids wearing garbage bags and shower caps and goggles...big tarps in the school yard...making predictions on a board...

I put up a board at the end of the year asking students which clubs they'd like to have next year, and this would likely fit the requests for gross club, science club, nerd club, art club, math club, possibly cooking club, (though not likely poo club)...

With more slow-motion. Also, a juicier-looking watermelon.

If these guys weren't such a bunch of sissies, they would just shoot the watermelon.

(Happened to see that yesterday; the rubber-band video just made me wonder why people have it in for watermelons all of a sudden.)

Also: In the grim darkness of the far future, there are only watermelons.

I am dissatisfied with the parameters of this experiment. It did not show how many rubber bands it takes to make a watermelon explode. It merely showed how many rubber bands it takes to bisect a watermelon. I suggest an improved layout of rubber bands, rotating the position of each band from the last. This would apply force more evenly across the surface of the spheroid.

There's also a whole genre of videos on Youtube where they play around with a massive amount of virtual watermelons with the Oblivion game engine. Here is one example.

I actually would be interested in how many rubber bands it would take to crush a human skull. We must be stronger than a watermelon. I hope.
posted by DU at 11:45 AM on July 21, 2012


I'm pretty sure I'd give up the ghost somewhere on the near side of 500 rubber bands.

Holy shit, their eyes close reflexively before the watermelon could possibly hit them. That's impressive to me to see in slow motion.
