1 airtight container 

1 5 oz bottle of clear glue 

½ cup water 

½ tsp baking soda

1 tbsp contact solution

Small Rocks 

Small bowl

What You’ll Do

In a bowl, pour the entire 5 oz bottle of clear glue.  

Add in ½ cup of water.

Add in ½ tsp baking soda and stir.

Add in the rocks.    

Add 1 tbsp contact solution.  It will instantly begin to form.

It will be STICKY!  Don’t panic!  Mix the solution in the bowl until it starts to form.

Knead the slime until it is no longer sticky.  

If you want to add additional rocks, go ahead!

Store in an airtight container.

Note: This is a heavy slime.  The weight from the rocks will make it cascade and stretch, but it is fun for molding into shapes too!
