Mixing Experiment - Blubber Glue Ball

 
Making a Blubber Glue Ball
Materials you will need:

• Water
• White Water Soluble PVA Glue
• Borax Powder
• Measuring Jug
•Small Clear Container
•Tablespoon
•Food Coloring (optional)
 
This can be a very messy experiment and therefore you may want
to conduct this experiment on a protected surface or outside on
a nice day.
Steps :
  1. Pour in around 12 oz. of water into your measuring jug and then pour into a small see through container (bigger than your hand).

  2. Spoon a heaped tablespoon of the borax powder into the water.

  3. Optional : put in a couple of drops of the food coloring of your choice.

  4. Stir this mixture to dissolve the borax powder until it becomes a white and cloudy solution.

  5. Let this solution sit until the water becomes clear and a bit of un-dissolved borax powder is at the bottom of your container.

  6. Slowly pour about 2 tablespoons of the PVA glue into the water solution.

  7. You should see a stringy blob of plastic matter floating in the water solution.

  8. Grab as much of the blob (with your hand) as you can and take it out of the solution. Be warned that this blob is going to be very gooey, slimy and slippery.

  9. Gently squeeze, roll and transfer the blob from one hand to the other. While transferring the blob from hand to hand it will become less slippery. At this point you may want to put it and your hands under some running tap water and then continue squeezing the blob from hand to hand.

  10. Continue until the blob becomes blubber and starts to form a ball shape.

  11. You can try throwing your ball against a flat surface to see what happens.
