Before I have a larf - and possibly end up with a contribution to the
Humour FAQ - what is going to happen, and should I mix CA and expanding
foam?


Most CA will eat expanding foam in seconds. Polystyrene anyway

CA and bicarb reacats very quickly and gives off a bit of heat to form a
sort of hard plastic foam. TYhin CA is the most amusing. It should smoke
a bit. The fumes are acrid tho...
