Bubble Lab

In this lab we are experimenting with the effects of adding sugar (sucrose) and salt ( sodium chloride) to a regular bubble mixture to see how it makes the bubbles react. 


In this lab, you will learn what the effects of adding sugar and table salt to a mixture for bubbles. 
The purpose of this lab is to test the hypothesis that bubble making can be affected by adding sugar or salt to a bubble-blowing mixture. 


The materials you will need is: 
  • 3 plastic drinking cups
  • liquid dish detergent
  • measuring cups and spoons
  • drinking straws
  • water
  • table sugar and table salt
Procedure: 
  1. Label 3 drinking cups 1, 2, and 3.
  2. Measure and add 1 tsp. of liquid detergent to each cup.
  3. Use the measuring cup to add 2/3 cup of water to each drinking cup.
  4. Then swirl the cups to form a clear mixture. 
  5. Add a 1/2 tsp. of table sugar to cup 2.
  6. Add a 1/2 tsp. of table salt to cup 3. 
  7. Stir each cup for 1 min.
  8. Dip the drinking straw into cup 1. Remove it and blow gently into the straw to make the largest bubble you can. 
  9. Repeat step 8 with the mixtures of cup 2 and 3. 
Results: 
After completing the Bubble lab, we found the outcome of adding sugar(sucrose) and salt (sodium chloride) to the bubble mixture. When we added the sugar, it had bigger bubbles. The salt mixture could hardly produce bubbles at all.  








All in all, this lab was fascinating and i would recommend doing this as a fun experiment!!!!
