# 🧪 Science with Sarah: Oobleck Slime at Reaching Maximum Independence ⚗️🧫

## Make a type of slime that acts as both a solid and a liquid

Hello parents, teachers and students! If you’re looking for fun way to explore states of matter and solubility this experiment is for you! Today we’re doing a fun sensory experiment with the folks at Reaching Maximum Independence -- a local non-profit which helps people with Intellectual Developmental Disabilities live life to their fullest potential!

Be sure to check out GMSA@9 on Wednesdays when Meteorologist Sarah Spivey does the demonstrations and explains the science behind it.

### HERE’S WHAT YOU’LL NEED

• A large container
• 2 cup corn starch
• 1 cup water
• Food dye (optional)

### MAKE THE OOBLECK

• STEP 1: Measure out 1/2 cup of water and add the food dye to the water
• STEP 2: In the large container, place 1 cup of cornstarch
• STEP 3: Pour the colored water into the large container with the cornstarch and mix using your hands (NOTE: This will be messy! Make sure to have plenty of paper towels nearby and maybe use an apron to cover your clothes!)
• STEP 4: Try compressing the oobleck in your hands into a ball. Observe how it quickly “melts” into a liquid.
• STEP 5: You can store your oobleck in the fridge to use for later. When you’re ready to dispose of your oobleck, throw it away in the trash. Large amounts of cornstarch should not go down pipes.

### HOW IT WORKS

Because cornstarch is not totally soluble in water, it can make a non-Newtonian fluid when combined with water.

A non-Newtonian fluid does not follow Newton’s laws of viscosity. That may be a mouthful, but basically oobleck it is a fluid that can exist both as a solid and a liquid depending on how much force you use!
