You can make a coin disappear with just water. 🪙💧 @AlexDainisPhD breaks down this optical science. As water fills the glass, light from the coin bends while passing through multiple materials, redirecting what you see so the coin is hidden from view. The coaster blocks where that light ends up, making it seem like the coin has vanished. Change the setup slightly by adding water on top of the coin first, and the illusion no longer works. #STEM #ScienceExperiments #Science #WomeninSTEM #ScienceDemo #YouTubeShorts #Shorts Everyday Awesome with the Museum of Science: https://www.youtube.com/watch?v=svRnHvj985s Women in STEM with the Museum of Science: https://www.youtube.com/watch?v=ZAkjNs-JS1I&list=PLxeUBLGfcIB9JQUT8YhlMsVxXU4P-h8rz&index=1 Short Science with the Museum of Science: https://www.youtube.com/watch?v=NkMj1NlZSs8&list=PLxeUBLGfcIB9dB6n8zqwu_w2vG6DmLsKy&index=15 Among the world's largest science centers, the Museum of Science engages millions of people each year to the wonders of science and technology through interactive exhibitions, digital programs, giant screen productions, and preK – 12 EiE® STEM curricula through the William and Charlotte Bloomberg Science Education Center.
