The only drives currently which are completely

if anyone else makes a helium drive yet or not. There
isn't a lot of helium to be wasted any more. The price
is getting quite high.)

Where I live, a dollar store sells helium baloons for a dollar.

I see people buy 5 at a time. It's terrible and such a waste. You
can learn all you need to know from one balloon.

There should be a 3000% excise tax on helium.
