Come for the slime, stay for the treats!
Stir up some spooky science at The Tech Interactive’s Spooky Slime Workshop, happening during our Tech-or-Treat Halloween celebration!

Unleash your inner mad scientist as you mix up your own delightfully ghoulish slime and discover the cool chemistry that makes it stretch, squish, and ooze. It’s hands-on, wonderfully messy, and just the right amount of spooky. Best of all? You get all the slimy fun without the cleanup at home!

After the workshop, keep the Halloween fun going with Tech-or-Treat festivities throughout The Tech. Come for the slime, stay for the treats, and make a whole day of spooky science and discovery!
