Procrastination Level 9000: Make a Vortex Smoke Ring Cannon using a round box, a condom and a e-cig!

If you don't have a condom you can also use a ordinary balloon. Half the fun - but when on kid's parties probably the better idea.

You can also use tobacco or any other herb to produce smoke by burning it but the e-cig creates dense smoke that doesn't stink. As an e-cig is essentially a fog machine, you can also use one of those.

Anyway, kids: NEVER START SMOKING!
