Collect 5-10 empty jars, buy a gallon of highly flammable liquid (I recommend acetone). Fill all jars with liquid, screw lids on as tight as you can.

Make a medium-sized fire outside (park, woods, garden) and make sure it's burning regularly and at a high temperature.

Place all the jars in the fire (for example with a pronged fork or a spade).

Take one step back and watch closely. Spectacular!
