Just like joker man says above just go and buy a cheap ass plastic cracker you don't have to go to a head shop those dam things have to be on the net somewhere ? Thats all you need and you are good to go man. Make sure you get the big ballons made for them becuse regular ballons will not work at all. Shit Some ballons can hold 3 or even 4 cartridges at a time.Other then that don't fuck around trying to use anything else you will just waste all the N2O or get frost bite on your fucking fingers-LOL I just found a few of my old crackers the other day. Also don't ever buy one of the big Fansy metal crackers that cost Mad loot they work like total shit and you don't get a good hit at all and they always end up breaking. The best thing for those cartridges is the cheap plastic crackers. Good luck man finding away to suck those bad boys down ????
^^thanks buddy but again people, my parents only give me money for amazon... why? Because amazon sells nothing bad, I tried looking for fucking whip cream cans and guess what...they don't even sell that!! But I can buy Crackers and Whippets so yea I will just have to wait till my parents give me more money to use on amazon.
