is it necessary to use a balloon? i am planning on buying a cracker and a box of whip its but in the mean time im just gonna get some reddi whip. ive heard rumors of people having lung damage from not using a balloon. so basically is it cool if i just suck it straight out of the reddi whip can and not with a balloon? also does the temperature of the reddi whip have any effect on the safety of doing it with out a balloon?
