Moving CHADS Experiment - The Weird Science Behind It

This amazing experiment always yields excellent results. When the contents of the bottle are poured into the cup, the chads will be floating on the interface between the water and the oil. But they will all be oriented in the same direction, with the dark side up and white side down! Welcome back to Kids Fun Science! Today, we're diving into a captivating **science experiment** that's perfect for **science for kids** to enjoy. This **do it yourself** project, the Mysterious Moving Chads, is one of our favorite **cool science projects** to try **at home science**. Watch as we demonstrate the steps to create amazing moving patterns with simple materials! Moving CHADS Experiment - The Weird Science Behind It The Mysterious Moving CHADS - non polar substances are attracted to other non polar substances Made for teachers and parents The Mysterious Moving CHADS To demo that non polar substances are attracted to other non polar substances. SAFETY: Perform only under adult supervision. Mineral oil is poisonous.

These will be dark with pencil on one side and blank on the other. * Add a little water to the bottle. Add about 1 cm layer of Mineral oil. * Add the chads to the bottle, replace the cap and shake for 15 seconds and pour the contents into a plasitc cup. Observer the orientation of the chads. Science behind this Mysterious Moving CHADS This amazing experiment always yields excellent results. When the contents of the bottle are poured into the cup, the chads will be floating on the interface between the water and the oil. But they will all be oriented in the same direction, with the dark side up and white side down! A pencil “lead” is not really made of lead, but graphite, which is a form of carbon. As are all pure elements, graphite is non polar in nature. Mineral oil is also non polar. Therefore the non polar graphite side of the chads will always be attached to the non polar mineral oil. This is further verification of the principle that “like dissolvers like”. Fun Facts Chad - The small circle of paper that falls on the floor after you use a hole punch is called a chad. Some voting machines work by punching holes in ballots, leaving a chad hanging from the back. The chad that falls off a card or piece of paper is a waste product of hole punching, often in the process of voting or punching a time card. The word chad was first used in the 1930s, but most Americans never heard it until the 2000 presidential election, when some votes in Florida were contested because of partially-punched ballots with chads still attached. Chad (noun) a small piece of paper that is supposed to be removed when a hole is punched in a card or paper tape
