Marshmallow Launchers

In K-2 Morning STEAM we made marshmallow launchers! They flew so far! Students followed a pattern to get the launcher working, but modified their creations so that they could hold marshmallows in a reserve and some students even made their launcher have a disguise. Once they made their launchers they focused on creating targets! They were very excited and couldn't believe when I let them all aim at me for a slow-motion video (have no fear- I wore safety goggles).
