Bring your family to the John T. Rettaliata Engineering Center Atrium after the Pumpkin Launch on Saturday, October 15 to warm up with hot chocolate and apple cider.

Armour College students from the Material Advantage group will amaze your guests as they use liquid nitrogen to make gooey candy as hard as a rock. You can also freak out your family by making a slimy non-Newtonian substance, also known as gak, with the AIChE student group. Demonstrations will take place from 2-4 p.m.
