Try this with a tantalum capacitor. Careful not to lose an eye...

Luckily our eyes tend to be closed when we're asleep. Evolutionary safety squints.
I'd like to see a study on the threshold of projectiles versus safety squints. I searched around, but couldn't find a paper.
LEDs also work if you've got enough energy to dump into them. Think bulky high-voltage cap + beefy MOSFETs.
