One of the reasons why we do so much science for kids here at Kids Activities Blog is because basic science is simple play!  Many favorite childhood activities could be broken down into a science lesson that kids just innately learn. Today we are doing bath tub science!  This floating cupcake activity was inspired by our sponsor, Mr. Bubble. floating bath tub science - Kids Activities Blog  

Bath Tub Science Experiment

There are a few things you can pull together before you head to the bath tub.  For this activity you will need:
  • Cupcake liners – aluminum foil or silicon work great.  You could also use small plastic storage containers.
  • Sponge(s)
  • Scissors
  • Mr. Bubble Original Foam Soap for “frosting”
Use the bottom of one of the cupcake liners as a template to cut the sponge into two circles for each cupcake liner you are going to use.  I suggest that you use at least 2 for this experiment which would be 4 sponge circles.  Safety scissors don’t work well on sponges, so this is one area an adult will want to take over. bath science activity materials    

Prepare the Tub

Head to the tub with your cupcake liners and sponge circles.  No bath is complete without bubbles so adding a few drops of Mr. Bubble 3in1 or Mr. Bubble Original Bubble Bath under the running water will set the stage for the perfect tub laboratory. Have kids float the cupcake liners in the water.  Ask them if they think the cupcake liners will sink if they add a  dry sponge circle. What about two? Then get one of the circles wet.  Does the cupcake liner still float?  Is it sinking in the bubbles? How much water do you have to add to sink the cupcake?

Make Bath Tub Cupcakes

Squeeze the water out of the sponge circles until the cupcake liner will float with both circles in place.  Grab Mr. Bubble Original Foam Soap to create “frosting” on the top of the cupcakes. bath tub cupcakes - Kids Activities Blog Kids can use the sponges covered with Mr. Bubble Foam Soap frosting to clean up!
