Bubbles: Predicting Which Solution Makes the Best Bubbles

Bubbles, bubbles, everywhere!  It is finally nice outside and time to get out the bubbles!  Jelly Bean and Jumping Bean love to play with bubbles, but today we decided to conduct an experiment with our bubbles.  The question: what will happen to the bubbles when a substance is added to bubble solution?  Will the bubbles form, will they get bigger, or will the bubbles last forever (that was a common prediction)?


First, we had to make our bubble solution. This bubble solution is your common, everyday bubbles made of water and dishsoap.



After dividing our bubble solution into six cups, we added a different substance to each one. Here, the girls added honey and food coloring. To their amazement, the different liquids layered like the liquids from our Float-Sink BLAST showing the different densities.



Now, the fun begins- blowing bubbles to see how they will change. We started with regular bubbles and had fun blowing and popping the bubbles.


Jumping Bean had a great idea! Make our own wands similar to the ones from our Bubbles BLAST.


The colored solution actually made colored bubbles! It was fun seeing green bubbles floating around in the air.



Experimenting with the bubbles was a lot of fun!  We were all surprised by some of the outcomes.  The bubble solution, without anything added, surprisingly did not make the best bubbles.  They popped pretty quickly.  The solution with molasses made terrible bubbles!  They didn't form at all.  The mixture with sugar didn't form well either.  The sugar didn't dissolve and stuck to our wands.



And, Jelly Bean's conclusion was that the bubble solution with honey made the best bubbles because they are stickier!  Bubbles with oil came in a close second.  The oil made the solution slippery which made the bubbles come off the wand easier.  At least according to four year olds.

Supplies:
  • water
  • dishsoap
  • 6 containers (we used cups)
  • 1/6 cup of each substance- honey, food coloring, oil, molasses, sugar
  • spoon for mixing
  • bubble wands
  • tape
  • marker

Instructions:
  1. Make the bubble solution by mixing one cup water with 1/3 dishsoap in each container.
  2. Stir until incorporated.
  3. Add 1/6 cup of each substance into one cup of the bubble solution. 
  4. Mix well.
  5. Label each container with the substance inside.
  6. Make predictions about what will happen to the bubbles with the different substances mixed in.
  7. Blow bubbles!
