here is a good one: 30% hydrogen peroxide, borax soap, and potassium chloride
peroxide in beaker...put soap in
pour in aqueous potassium chloride
SUUUUUUUDS
(borax doesnt dissolve in H202, potassium chloride makes the extra O bubble off, soap dissolves, bubbles cause suds, bigtime soap)
According to my calculations, a briefcase-sized setup could fill a LARGE room, I'm tempted to do this |
