A device used to "
crack" the seal on Nitrous cartridges for inhaling the N20 for a high. The cracker is commonly aluminum, brass or plastic and simply accepts a N20 cartridge (intended for dispensing whip-cream) and pierces the seal, allowing the
gas to escape in a controlled fashion. A baloon is attached to the device to capture the
gas and allow it to absorb enough heat to be inhaled safely.
