What is Zip Stick?
The end result of when you take an ordinary stick and tie a plastic bag very tightly to the end of it. You then proceed with lighting the plastic on fire until it melts thoroughly the lift the stick high into the air. The platic will begin to drip off and with each drip, it gets super-cooled and making a nifty little "zipping" sound.
We made many zip sticks at our bon fire last night. Pascal thought he'd be cool to catch one of the flamming drops of plastic. He regretted it 3 milliseconds later.
