That's at my house.
Ahh the plate, the great plate!!!
Here's what you do, get 2 girls and tell them that if they put one of their hairs into a plate full of water that the hairs will actually fight each other. You get everybody in close to see the hairs in the water and you tell them to look closely as you can see them fighting each other. You have to look really close...Then smack! Slam your hand into the plate of water getting everyone who was stupid enough to believe you soaking wet!
The girls were in on it as I got them a couple of years ago. It was 3 in the morning last night and these 2 guys fell for it hook line and sinker. That's me in the yellow.

Here's the aftermath of the smackdown, as you can see by the trajectory, both of them get it right in the face!!!
