Mystery Layered Soda
This experiment will not only “wow” the kids but they’ll get to drink their concoction as well. Fill a glass with ice and then try layering different colored beverages on top of one another – those with the highest sugar content at the bottom (relative density) and working your way to the top. It’s magic! Get directions

Fill a bowl with whole milk, add a few drops of different colored food coloring, and then place a drop of dish soap on top of each color. Watch the bursts of color appear as the soap breaks down the fat in the milk creating a colorful display. Get directions

Sparkling Pennies
Make your old, dull pennies shine again. Using a mixture of vinegar and salt in a shallow bowl, add the pennies and then count to 10. Rinse with water and look at them shine! The acid in the vinegar reacts with the salt to remove copper oxide which was making your pennies dull. Get directions

Homemade Lava Lamp
Fill a recycled water bottle with ¾ cup water and the rest of the way with vegetable oil. Add about 10 drops of food coloring. Add ½ of an Alka Seltzer tablet and watch the lava lamp appear. Originally the oil sits on top of the water because it is less dense. When the tablet is added, it creates gas and the gas bubbles rise taking the colored water with them. Get directions

Diet Soda & Mentos Geyser
For the grand finale, we’ll create a spectacular display simply using diet soda and Mentos candies. The many small pores on the candy combined with the aspartame in the diet soda cause a very fast release of carbon dioxide gas in the soda which creates a spectacular, if not messy, eruption.
