Learned as a teen that two household chemicals could be combined to make a very unstable explosive :eek: In college chemistry I mentioned it to a classmate. We had the ingredients right there on the lab table with us. He made some, the sediment from the reaction was the noisy part and very little pressure would bring about the detonation. He filtered out the sediment on a sheet of filter paper and hung the filter on the wall for it to dry. Some of it fell of the filter while still wet and semi stable. It dried on the floor. Female classmate walks by his station and stepped on that compound, blew the heel of of her shoe. I've always been convinced these Poppers are made of the same stuff.
