Magic Milk: Take milk in a plate and add food coloring. Then you take a drop of soap (either on your finger or a qtip) and dip it into the milk and the food coloring will 'start to dance'. This occurs because the soap molecules are finding and bonding with the fat molecules in the milk.
Baggie and Water Magic: Take a plastic zip lock bag and fill it 3/4 of the water with water and seal it shut. Hold the bag in one hand firmly push the pointy end of the pencil through the bag and continue pushing until the point comes out the other side of the bag. No water spills out the holes because Ziploc bags are made of a polymer and polymers have long chains of molecules that are flexible. When you poke a sharp pencil through the baggie, the pencil slides in between the chain of molecules that make up the polymer. The molecule chains make a seal around the pencil that won’t let the water out.
This experiment will be all about a balloon inflating without actually blowing it up. First off, fill the bottle halfway with vinegar. Then use the funnel to put a teaspoon of baking soda into the balloon. Then, making sure none of the baking soda gets into the bottle, stretch the opening of the balloon until it’s completely over the opening of the bottle. Once the balloon is attached to the bottle, lift the rest of the balloon so that the baking soda falls into the vinegar. Then watch the balloon inflate without actually blowing it up!
Materials Needed: For this experiment, you will need an empty water bottle, a balloon, vinegar, baking soda, a funnel, and baking soda!
