Cohesion in Parshas Beshalach

Item Number: CRSHM14-RS031

Date Submitted: 02/11/2015

Not yet reviewed | Write a review

Cohesion is a liquid's molecules' natural tendency to stick together. In Parashas Beshalach, Hashem caused the water to resist its natural tendency of cohesion and split apart! In this experiment, students will see how two different colored drops of water merge together to form a new color. Once the drops have merged, they cannot be separated again.
