ILHS science teacher Mr. Dunn was replaced by his evil twin once again for Halloween! This “mad scientist” took over his classes and wowed his students with several spooky, slimy and expanding science experiments during what he called the 8th Annual Halloween Science Spooktacular. Among many demonstrations, they made dry ice bubbles, troll snot, jack-o-lantern vomit and more. Students suited up with safety glasses and went to the back of the classroom for the grand finale--"how mad scientists carve pumpkins!"
