I have tried the the 6 cracker thing.  Ya, it's not gonna happen.

Now if you really was to see something funny.  Challenge someone to try and drink a gallon of milk in one hour (without puking).  They can't eat anything during that hour.  It seems easy, but I have yet to see someone do it.

the beer bottle thing only works for non-carbonated liquids.

i saw it first on Time Warp too and they said that it wasn't the force of the air that caused the bottom to pop out, it was the fact that the pressure difference caused the water to lift up and then the vacuum below the water sucked it back and it busted the glass. then they tried it with beer and the air space that formed under the beer just got filled up with fizz and the trick didn't work.

so after watching that i immediately went out and tried about 6 bottles worth of this trick. i could never get them to pop on the first blow, always on the second.

oh, and everybody at the lunch table was CONFIDENT they could do it, and out of 5 people, everybody failed.

one kid was breaking the crackers with his hand as he was eating them, and when the minute was up, he had just half a cracker left to eat. i'm not sure if this is against the rules or what.

Try a teaspoon of cinnamon....

For real, one of the funniest things you can watch...
