In this video I test several experimental projects with an oxygen concentrator. There was no script for this one so you get to see a bit of my experimental process.

Thank you to everyone that supports this channel on Patreon! A special thanks to my top patrons: Teague Lasser, Eugene Pakhomov, Evan Hughes, Edward Unthank, and those who have chosen to remain anonymous. Thank you!
