Piers, that dinosaur glue was, indeed, quite sticky. But this was public school. We couldn't afford top-of-the-line stuff like that. ; D

As for the maracas (same method) and puppet heads being grey, that was only before we put that new-fangled coloring stuff on them.   It was called "paint."

"Tempera paint," in fact. I think it's made from eggs. Then we'd cover that there "paint" with another high-tech stuff called "shellac" (which is made from dead bugs).   

The maracas were quite colorful, and the broken glass - for the maracas, we'd break the lightbulb after the whole papier-maché maraca was a closed unit - made a nice, tinkly percussive sound.   The puppet heads didn't really look like lightbulbs if you used enough papier maché to mold whatever facial shape you wanted, and the heads were very colorful too.    I still have 4 of the ones I made back then, and the colors are still bright.
