Just your average DIY enthusiast about to create the world's most exciting water! Looks like someone discovered IKEA's new "Universe Starter Kit" - just add hydrogen, oxygen, and a complete disregard for laboratory safety protocols.
For those who slept through chemistry class: combining hydrogen and oxygen creates H₂O (water), but with a slight side effect of a massive explosion that would vaporize both our bespectacled friend and half the neighborhood. Nothing says "I'm a science genius" quite like assembling water molecules the spicy way!
The instructions probably say "Step 1: Combine gases. Step 2: Enjoy your new crater."
