Weird Glop (Oobleck)
Almost everything in the world is a solid, liquid or gas. Things can change from
solid to liquid to gas. It changes to a solid when it freezes. When it boils and you see
steam, it has become a gas. Weird glop isn't really a solid or a liquid. Do not eat it!
In order to make weird glop, you will need:
1/2 cup cornstarch measuring cup
1/4 cup water bowl
spoon food coloring
Instructions:
1. Place the cornstarch in the bowl.
2. Pour the water into the bowl a little at a time while stirring.
3. Keep mixing until all your glop looks and feels the same.

Balloon Blowing
Try to blow up a balloon without using your own breath. This will take several people
working together.
You will need:
1/4 cup vinegar
A small plastic bottle (with a neck over which you can place the mouth of the
balloon)
2 tablespoons of baking soda
A small balloon
Instructions:
1. Pour the vinegar into the plastic bottle.
2. Stretch open the balloon mouth and carefully pour the baking soda into the
balloon.
3. Place the balloon mouth over the bottle. Make sure the balloon mouth is tightly
around the neck of the soda bottle.
4. Hold the balloon to the side so that the baking soda does not fall into the bottle.
5. Shake the balloon so that the baking soda falls down into the bottle.

A Butterfly of Many Colors
The ink in a black felt-tip pen is made from chemicals of different colors. Mixed
together, these colors look black. How can you see the different colors?
You will need:
A black, water-soluble, felt tip pen
A coffee filter
Scissors
1 cup of water
Instructions:
1. Fold your filter in half and cut out a butterfly shape.
2. Using your felt tip pen, run a heavy black line down the center of the fold (open
your filter so the whole body of the "butterfly" shows and draw down the center of
it's body).
3. Dip the filter into the cup of water.
Watch closely, but don't touch the filter. What happens?_________
