Next, we made eruptions by pouring vinegar onto a cup of cornstarch. We used pipettes to control the amounts. Kool-aid mixed in made our experiments colorful and good-smelling! More vinegar made more bubbles! What a reaction!
Finally, we got creative by adding all sorts of liquids (and solids!) to our potions - soap, apple cider vinegar, even oil. Glitter made it sparkle, heart candy floated through it. Fun!
Even after you stir and stir and STIR, cornstarch, vinegar, and oil each make their own layer. Isn't it a pretty potion?
Next STEM Saturday - November 7th at 10:45. We'll be experimenting and having fun with marble runs!
