The Disappearing Stamp
Let me tell you about a really cool science trick. It’s called the Disappearing Stamp. It works by having a cup of water, postcard and a stamp. You put the stamp under the glass of water then you place the postcard on top of the glass of water. After that’s done it looks like there’s no stamp. The experiment worked by having the light rays refract downwards toward the bottom of the cup of water, which then hits the bottom of the cup then the rays are refracted upward and into your eyes causing you not to see the stamp. It is really cool!
