Hooked on Science: Portable heater
Ever wish you had a portable heater? All you need are a few items from around the house to create one.
* Zippered sandwich bag
* Hydrogen peroxide
* Dry yeast
STEP 1: Pour half a cup of the hydrogen peroxide into the bag.
STEP 2: Add one teaspoon of dry yeast to the bag.
STEP 3: Close the bag and mix the ingredients.
STEP 4: Touch the sides of the bag.
The warmth from the bag is created due to a chemical reaction taking place inside the bag. A chemical reaction that gives off heat is called an exothermic reaction. Discover more hands-on experiments by going to www.hookedonscience.org.
