Cornstarch Goop

Ingredients

• 1 part cornstarch
• 1 part water
• Food coloring, optional

Directions

Mix the ingedients together in a large bowl. Then, pick up the goop and squeeze it - it's crumbly. Hold it loosely - it oozes through your fingers. Knock on the mixture (inside the bowl) and you will find it feels hard. Put your finger slowly into it and... it is liquid. It's solid one minute, liquid the next. Magic? No, Science.
