Materials
Bar of Ivory soap
Microwave
Towel or paper plate
Directions
Cut the bar of Ivory soap in half. DO NOT put the entire bar of Ivory soap in the microwave at once unless you want a huge mess! Cut the halves in half to make four quarters of the soap. Place 1/4 piece of the soap bar onto a paper plate and heat it in the microwave for 1-2 mins.
WATCH what happens! The reaction happens quickly so watch it & stop the microwave when appropriate. Remove the plate and allow your child to explore the soap. You may want to move the soap explosion to a tray or plastic container. Heat the remaining bars, 1/4 at a time.
Extension: Try adding a little bit of water to the soap. Ask your child to describe the different textures.
