What are some easy ways to get high with household things?

I've heard, that if you take 5 or 6 Ny-Quil you can get high. Be careful with that its pretty crazy and it lasts a while. Other than that, if you have whipcream in a can, let it sit for a while point it up right and spray in to your mouth and inhale you can get a buzz, its pretty much laughing gas in a can.
