STEM Celebration Experiments
STEM City Center challenged students to do something "STEMmy" with a small plastic test tube. We just received our first experiment: Arlo Millis writes "We mixed vinegar from test tube with baking soda." He sent us this great video of a wonderful reaction of an acid (vinegar) and a base (baking soda) that many people use to clean their drains.
Thank you Arlo and don't forget to wear gloves and your safety goggles!
