That's pretty creative problem solving. I doubt I would have come up with that.

^I would have used human problem solving: Violence, more violence and if that doesn't work even more violence.
Repeat until problem is solved.

Unnervingly I think LarsaruS is right. I'd probably have looked for something to break the tube with. I certainly wouldn't have been thinking as creatively as the chimp.

He should teach reasoning skills at Glenn Beck UniverCity.

I think the problem is that the item is food, and one that's not normally eaten wet. If we were asked to get something that we suspected could float and wouldn't be harmed, we would think of water.

Then again, when I clicked on the link, I expected the chimp to pee in it. I didn't see that he had access to lots of water, but I suspected that he had access to lots of pee.

Feces!

On a good day?

NOT a dupe, but I knew I'd seen this before!

EIA please

How the hell did he know that the peanut would float? Clever!

Ya...I didn't know peanuts floated. I wonder if they float with the shells off too...TIME FOR KITCHEN EXPERIMENTS.

Also, I wouldn't have wanted to get it wet =\

I only knew that peanuts floated 'cause my dad always popped some into his glass bottled root beer for some reason...

Nice job, monkey. If it had been a competition between you and I, I would've been mighty embarrassed.

But it wasn't a pingpong ball. The monkey figured something out that many of us wouldn't have. I might have looked for a stick, but I certainly would have gone the violence route before that idea struck me. Planet of the Apes, here we come!
