Elephant's toothpaste is a foamy substance that's created when you combine water, hydrogen peroxide, yeast, and dish soap. It is commonly used as classroom experiments to demonstrate an exothermic reaction. More recently, it's been used at the 2019 Miss Virginia pageant and for gender reveals.

This video shows you how to wind a large coil of wire (sometimes called an electromagnet or a solenoid, depending on the context) using a power drill. If you are just making a small coil that requires a few dozen wraps of wire, it is easy enough to do by hand. However, if your science project requires a large coil with hundreds or even thousands of turns, this can take a very long time to do by hand. A power drill can speed up the process and make it a lot easier.

Get water to "walk" from one cup to another in this colorful science experiment. Capillary action moves colored water from full to empty cups. For some bonus fun, add dyes to the water and watch the water mix to form whole new colors! Full science activity instructions and a detailed explanation are available at: https://www.sciencebuddies.org/stem-activities/walking-water?ytid=s2Jud7F478I&ytsrc=description

Acids and bases can be found all throughout your everyday life and are often times very useful… even in your own body! But what is it about acids that make some super dangerous and other safe to eat? And in order to tell how acidic or basic a chemical is, how do we measure their individual intensities? This episode of chemistry basics covers the fundamentals of acids and bases and how we use the pH scale to measure them.

Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random DNA copying “mistakes” account for nearly two-thirds of the mutations that cause cancer. Their research is grounded on a novel mathematical model based on DNA sequencing and epidemiologic data from around the world.
