Today I made a 🌈.
I used a mirror and a fantastic glass with water 💦. We shone a torch at the mirror in the glass of water but a rainbow didn’t come. Then we tried a torch and a CD. We shone the torch at the CD and a rainbow appeared!
Then we did some tricks with a pencil and water. We put the pencil in the water and it seemed like the pencil was broken. It looked bent but when we took it out it looked fine! You should try it! It is called REFRACTION.
