As we approach the first of April, we're getting into the spirit of April Fools Day. Check out these activities and see if you can be tricked by these (scientific) illusions!
🌈 Rainbow Catching
Let's make some rainbows of our own and see if we can catch them! There are a few ways to make your own rainbows:
1. On a sunny day, use a glass of water or a mirror to catch the sun, angling the water or mirror it to project it onto a wall
2. Outside, when the sun is low in the late afternoon, you can spray water from a spray bottle or misty garden hose and create rainbows
3. Fill up a glass of water and cut a thin rectangle out of white paper. Stick the paper onto the glass and shine a focus-beam flashlight so that the light shines through the glass, through the paper rectangle, and onto a wall. You should see a small rainbow that you can make, even in the dark!
Can you figure out other ways to catch your own rainbows?

🥣 Solid or Liquid?
In a bowl, mix at a ratio of 2 parts cornstarch to 1 part water (preferably with fun food coloring!) to make a physical illusion for kids to play with. This mixture is a Newtonian fluid that is sometimes known as "oobleck" from the Dr. Suess children's book Bartholomew and the Oobleck.
Poke, hit, sink, and play with it. What do you think: is it solid or liquid?
For more on the science behind oobleck, check out this video from Crash Course Kids.
🥛 Magical Milk
Pour some milk on a plate and use food coloring to create small pools of different colors around the milk. Now, get ready for the magic! Dip your finger in a little bit of dish soap and then poke the center of the plate and watch as the colors... oh, we don't want to spoil it for you - go try it and find out what happens!
Can you create magic with a single poke?

Hopefully you and your kids find a sense of wonder with these (scientific) illusions and have a fun April Fools Day!
