At first I thought "what a waste of watermelon" but then I thought "this is really really cool!"

ha!  that was EXACTLY my thought process!

I'm surprised at how entertaining slow mo is. http://pandawhale.com/ifindkarma/slow-mo

you have a whole stash of slow mo!!!

this watermelon video is the first time i have seen the slow mo cameras revealed and i was fascinated to learn that the one camera gets 5000 fpm and the other gets 4000 fpm.  that's a lot of frames!!

It really is -- it means they can slow things waaaaaay down if they want to!

so cool!!!

Yes. By the way, here's a slow mo toilet brush with a nail shot by slingshot through a watermelon:

Watermelons are excellent for slow mo.

i like that he ate the watermelon at the end!

It would have been a shame to waste that delicious watermelon!
