Bubbling Eruption 
In a pitcher, mix ½ cup of dish soap, 1 cup of water, ¾ cup of vinegar, and a squirt of liquid watercolor.
In a clear bottle put a ½ cup baking soda.
Using a funnel, slowly pour the vinegar liquid into the baking soda bottle.
A carbon dioxide gas is formed. The dish soap extends the reaction time and thickens the lava.

Knox Gelatin Mold
The ratio is 3/4 cup water to 1 packet of Knox. Take the number of cups of wat
er your container holds and DIVIDE by .75 This is how many packets of Knox you need. In a saucepan, heat the water over low heat, add the packets of gelatin. After it dissolves pour it into your container. Let set over night. **BE SURE TO SPRAY YOUR CONTAINER WITH PAM FIRST! Allow the children to inject the Knox mold with pipettes and eyedroppers filled with colored water!
For an extra twist, add a layer of shaving cream on top and let the kids experiment.

Flubber
1. Mix 2 cups water and 1 1/2 cup of white glue in a big bowl (we used 1 cup of glue at the demo and it was a little runny).
2. Add a squirt of liquid water color and then stir it up.
3. In a separate small bowl mix together: 2 cups water and 4 TBS Borax.
4. After it’s completely dissolved, pour the Borax mixture slowly and a little at a time into the glue and water mixture. Pour a little, mix it a little, pour a little, mix a little. Mix with your hands or a sturdy wooden spoon. As you mix, it will become a flubber ball! NOTE: You might NOT need to use all this Borax Solution!!!!!
5. Store it in an airtight container or Ziploc for a few weeks. When it begins to flick apart or when it gets too hard, it is time to make a new batch! Play with it, explore it, try to get it to blow a bubble with a straw! Watch it stretch as you hold it!
6. Vinegar takes it out of clothes, carpet and fabric. Mayo will take it out of hair!

Bouncing Bubbles
Mix 1 cup distilled water, 2 tablespoon Of blue Dawn, 2 tablespoons of glycerine or Karo syrup. The water is the most important ingredient. Good quality water doesn’t contain high levels of iron or minerals. Glycerine/Karo syrup gives the solution the extra strength. Use a glove on your hand and you can hold a bubble and make it bounce.
The original recipe called for 1 tablespoon of glycerine or Karo but we found that 2 tablespoons works better.
