Some guy making some cool things, including rail guns and gas turbines. There’s also some chemistry stuff aswell. There’s some videos and lots of pictures.
If you wanna play with hydrofluoric acid like they’ve done, a few tips:
1. Don’t.
2. Do it in a fume hood.
3. Cover your arms and wear a face shield.
4. Just don’t. 🙂
