Christmas toys you'll never see again

The most "lab" fun we had was mixing soda and vinegar and food coloring together and watching the test tubes overflow with froth. We also had a GIANT plastic "hypodermic needle" toy that served as a squirt gun.
I went as far as making gunpowder and string fuses. Put the gunpowder in an old model car, stick a fuse in the window. Light it and watch plastic burn, smoke and melt. Had a small carbide cannon too. My old man wouldn't let me play with the cannon without him nearby. lol
