Science Sunday: Glow in the Dark Potions and Goop

Credit for this activity goes to Growing a Jeweled Rose:

A black light might just be the best $16 I ever spent. We got ours from here.

We started off by making some glow in the dark water (must have UV light to get the glow going). 

Super simple: 

1. Take a sharp knife and start sawing at a highlighter

2. the casing will easily break open 

3. take out the highlighter ink and soak it in up to 6 cups of water

4. Done 

We started off with a glow in the dark volcano:

 Baking soda in cup and pour vinegar + glow water mixture over it

 Then we made some flubber using our glow water as well:

 

Here is the recipe we used for flubber:

Borax 1 tsp

Water 1 cup 

Glow water 1/2 cup

Elmers glue 1/2 cup (4 oz container)

1. Add 1 teaspoon of borax to 1 cup of warm water 

2. Add 1/2 cup of glue (4 oz container) to a 1 cup measuring cup and rinse glue container with warm water to remove all of the glue. The total amount of liquid water and glue should total 1 cup. Pour contents into a glass bowl and mix well with a whisk.

4. Pour the Borax solution into the glass bowl of glue mix. 

5. Mix with your hands for a moment, the goo should form almost instantly and pour out the small amount of extra water.
