Science + Halloween = a jack-o’-lantern fit for the Headless Horseman himself. An awesome high school chemistry teacher dazzled their students by creating this phenomenal jack-o’-lantern with bright green flames burning inside its head.
The spooky green fire is produced by burning boric acid and methanol together. Click here for instructions for how to make green fire. Just be sure to do it outdoors and very carefully. No one wants to get burned or, you know, summon the vengeful ghost of a decapitated Hessian soldier.
