Materials: Water 2 Tablespoons Corn flour Bowl Spoon
<ul><li>Put 2 Tablespoons of corn flour into the bowl </li></ul><ul><li>Add a Tablespoon of water to the flour and stir well with the Spoon. Keep adding small amounts of water until the Goo is thick and creamy. </li></ul><ul><li>Pick up the Goo and roll it in your hands, then stop rolling – What happens? </li></ul>
When you roll the goo, it feels dry and hard. When you stop roll, it slowly spreads over your hand like a liquid. Corn flour particles float in water. When you roll the flour and water the particles are forced together. When you stop rolling, the corn flour and water separate again. Corny Goo behaves like quicksand!
Materials: White PVA Borax Powder Green food Coloring Water
1.In a container, mix together one tablespoon of glue, one tablespoon of water and one drop of green food coloring. 2. In a different container, dissolve one teaspoon of borax powder in one tablespoon of water. Borax powder is poisonous so wash your hands after touching the slime or borax powder. 3. Pour the borax mixture into the Glue mixture and mix with your fingers-a slime should form instantly! 4. Store in an airtight container
The glue and borax mix together to make a new chemical-slime! The borax stops the glue flowing like a liquid. The slime is very elastic so it can stretch and bounce!
Materials: Flour Water Jar with lid Spoon Paintbrush
1. Mix 1 cup of flour with half a cup of water until it turns thick and gooey
This is a chemical reaction and the glue sets hard when its dry. It is also a non-toxic and edible glue-but it wouldn’t taste very nice!

The heat changes the lemon juice into a new chemical. This has a brown color, and so your message can be seen on white paper. Eventually, the paper would turn brown and burn but the lemon juice changes more quickly.
