its sorta cool. the stuffs great to play with...like... blow it through a cigarette... watch that thing burn! or into the flame of a lighter...anyone need an oxy torch? and being heavier than air, it makes your voice drop a few semitones in pitch...just like argon welding gas
the opposite to helium
into an engine? sorta silly. watch madmax2 for an idea of the end results
you hit trucks at high speeds....
yes, yes, ppl do it, i know, i know. it does work, but reliable setups are complex and expensive.
a cheap kit? if you do buy one...a tip. buy your bulbs through a hospitality industry supplier.... cream whippers are NOS, soda siphons are CO2. they are the cheapest bulk suppliers i know of. youll get twenty for the price of 5 on ebay... food/medical grade.
for anyone that understands the real operation of NOS in an engine... i say this. ive moved onto a far better alternative, thats cheap, liquid at room temp, non-flammable, technically street legal as its not commonly used...
its basically hyped up water... any guesses?
