Last time I tried, liquid came out.
it aint air its mostly gas like butane.
I.e. flammable or quite unhealthy.
1) Open your god damned windows faggot
2) hold can upright always
3) Give it a few bursts to ensure any liquid traped inside the riser/spout is expelled
4) Point it towards something you want to blow
5) open your mouth ..
Don't shake the can. Never hold it side ways or upside down. Stop spraying once the can gets cold and let it warm up and continue spraying.
It's essentially liquid air. If you hold it upside down, super chilled liquid comes out. I like to spray my brother with it. It leaves temporary freezer burn on the back of necks really easily. It's fucking hilarious.
It's a scam, get an air pump (like those for bikes), it's way better and economic.
