These kids don't seem anywhere as ingenious as our Explainer. They probably just lined the bottom with foil, used it as an old-fashioned water-pipe, and called it a bong.

Or, buy bong. Drill hole in skull, slide skull over bong, secure w/duck tape. Presto, skull bong!

What, we think our kids are craftsmen now?

When I was living in the Haight in the late 60's, we made a great one out of a 5 gallon jug from a water cooler, installed a bowl large enough to hold an entire lid and put 5 rubber tubes on it.
What great times we had.
A friend made one out of a rubber gas mask with big glass eyes in it.
You'd take a big hit and the thing would fill up with smoke and you couldn't see the smoker's eyes.
When he'd exhale, you could see his bloodshot eyes.
It was hilarious.

These idiots should have gone to a "head" shop.lol
