None of you fucker's will belive this. All I got to say is go to the store, and try it.
It was a friends birthday. About 15 of us were getting rowdy in a bar, drinking shots, and I was in true form. A couple of the guys made a paper roll that had about 20 Mentos in it. We were on the patio with a 2 liter bottle of diet coke (I believe it requires that exact recipe).
I'm 3 sheets to the wind. And I'm all fuck this you guys are amatures. I take the diet coke, and the mentos and go inside. Everyone follows me thinking I don't have the balls. I notice these two girls at the bar that were cunts earlier and go right next to them.
I call over the bartender and put a $20 bill on the bar. I tell him take a credit card. Put it over the mouth of the diet coke. Take this paper roll full of mentos and line it up over the mouth of the bottle. If you can pull out the credit card and drop all the candy in the bottle the $20 is yours. I told him that it's virtually impossible.
He was all "This is stupid". I reach for the bill, gloating I knew he couldn't, and he's all "Wait I'll take your money"
So he put a credit card over the mouth, takes about 3 minutes lining up the roll, then zips out the card, dropping all the candy in the bottle. He reaches for the money, when half the contents of the bottle violently erupt all over the ceiling, the bitches, the bar, the bartender, the bottles of booze, and all over the bitch's purse and cell phone.
Everyone at the birthday party was kicked out, and we can't go back for a month.
