Even easier is grasp the lightbulb by the metal base with the glass down and the center connector facing up. Smack that center connector with a heavy spoon or light hammer and it will shatter the porcelin and center support. Leaving you a hollow light bulb with a hole in the end. Takes some practice but super easy once you get the hang of it. It also leaves the threaded base intact so you can seal it with a bottle cap and tape instead of messing with wax.
2 problems here. 1. Plexiglass is resistant to common chemical glass etching solutions. 2. Those solutions contain some nasty chemicals and acids, FAR from harmless. Might as well be flinging battery acid or drain cleaner at that point.
Yeah this seems way too complicated. Water balloons seem like they'd be way easier to mass produce. If you want something which can't be washed off easily then just use oil based paint.
And sand.
When they wipe the paint off, the sand will scratch and "fog" the glass/plexiglass, which requires the goggles/camera/plexi shield to be unusable.
Balloons are actually pretty hard to pop, especially when not inflated with air. I don't think they'd work that well. You need something fragile that breaks on impact. There's a reason a lot of hand grenades meant to break and distribute their payload were made from glass or ceramic. I would guess that light bulbs are probably the easiest and cheapest way to get bulbs for this.
Water balloons are surely designed to pop and spray their contents. That's their whole point. Are you thinking of normal party balloons?
It is. I just wanted to share my crafting tips from when I was a young stoner making vaporizers. Balloons are definitely the better option.
I was just thinking, how is anything that can eat into glass not going to be corrosive to skin?
something something organic chemistry something something properties of silica?
hydrofluoric acid HF eats glass but if it gets on your skin in smaller amounts it will mostly just penetrate it, leaving it mildly irritated for some time. There it starts dissolving calcium from your bones and attacking nerves. HF be nasty
