This Penny Droplets activity & project also includes:
Compare the number of drops of pure water and soapy water that will sit atop a penny before spilling over.

Add this to other activities that demonstrate properties of water for a wonderful water lab!
- Demonstration done with everyday materials
- Fun for elementary and middle schoolers
- Exemplifies commonly taught concepts in physical science
