fa565. Fart Powder - Give them Gas YES, it really works GREAT! Made of harmless ingredients. I have been told this works so well that it can even make you burp! Mix in any hot drink or food. The person will not even taste it. Then sit back and watch them fart away just minutes later. It is funny as hell to do on someone. Think of all the times you can use this prank~!
