Rainbows are always magical & amazing when they appear in the sky. Although we can’t recreate the exact science of a rainbow in our own kitchens, it’s always fun to try. The Imagine Nation Museum recently shared their trick with Easy Rainbow Science Fun that’s perfect for all ages trying to answer the age old question of ‘Is there an end to the rainbow?’ According to this science experiment it just keeps going & going & going…
However, before you start any science experiment, always have the kids guess what is going to happen & record it so that they can compare their thoughts to their actual discoveries at the end.
- Food Coloring (all different colors)
- Dishwashing detergent
- Put a layer of milk on a plate, enough to cover the bottom.
- Using 2-3 different colors of food coloring add a few drops of each color in different areas on top of the milk (so that none of the colors are touching each other).
- Dip a Q-tip in dishwashing detergent , and touch the Q-tip in the middle of the milk
- After a few moments the detergent will spread to the food coloring, and swirl the colors together creating a beautiful rainbow.
Note: Be certain to tell kids that the experiment is not edible due to the dishwashing detergent used.
Real Rainbow Science Discoveries:
- Rainbows are kind of like an optical illusion
- A rainbow is formed because raindrops act like little prisms that catch the light
- The raindrops split the light creating colors for your eyes!
- No matter how you move, the rainbow will always be the same distance away from you
