Hooked on Science: Magnetic slime

Materials

• 1/4 cup liquid starch
• 1/4 cup Elmer's glue
• 2 tablespoons iron oxide powder
• Neodymium magnet

Instructions

STEP 1: Mix the liquid starch and iron oxide powder in a bowl. Add the Elmer's glue and continue to mix.

STEP 2: Remove the magnetic slime from the bowl, continue to mix the slime with your hands.

STEP 3: Hold the neodymium magnet close to the magnetic slime and observe.

Explantion

The Neodymium magnet creates a magnetic field, which is an invisible force. This invisible force causes the iron oxide, which is magnetic, to attract to the magnet.
