Rainbow Milk
Hi CDS friends & family! This week I chose to expand upon something I did earlier this year at school. Remember the milk explosion demonstration? I decided to try it again, but this time I will be using a baby swimming pool instead of a small tray! Watch closely for a new twist at the end! Click on the link below to see what happens!

That was an example of 2 chemical reactions. The first reaction was the soap reacting and chasing the fat in the milk, and the second was the vinegar reacting with the baking soda and forming lots and lots of carbon dioxide bubbles. How could we change this scientific experiment? I used whole milk in this demonstration. How about trying it with 1% or 2% milk? Or heavy cream or even water? Make a prediction each time and compare the results!

Looking Ahead: Wave Bottle
For our last science activity of the school year, I thought it would be fun for you to do an activity while I do it! Next week, I will be making an ocean in a bottle, also known as a wave bottle. The supplies you will need for next week’s activity include:
- An empty plastic water or soda bottle with lid
- Water
- Blue or green food coloring
- Cooking oil or baby oil
- Funnel (optional but extremely helpful)
- An adult may also want a glue gun or strong glue to adhere the lid on tight!
Join me again for science on May 27, and we can create a wave bottle together! If you cannot make a wave bottle with me next week, please do still watch so you can create one during your summer vacation.
