Put the water marbles in water and after several hours they grow about 200x the original size.
Use the water marbles as a sensory item in a sensory table.
Use the water marbles to count or sort. Have children sort them in foam egg cartons by color or number (write numbers on egg carton sections). Picture example shown but not included.
Use water marbles with plants. Place an established plant out of the dirt and place the plant root system in with the hydrated water marbles. The plant will absorb the liquid from the water marbles and the children will be able to view the root system. When the water marbles begin to shrink, just add more water. Picture example shown but not included.
Add 3 cups water for a full tube (1 ½cups water—half tube). It will take anywhere from 4-6 hours to fully hydrate.
When done using the water marbles you can let them dry up. Place the water marbles in an open container/bag. After several days the water marbles will shrink back to its original size. It can take 2-7 weeks to fully dehydrate and shrink. The water marbles will look funky like a raisin when dry but add water again and in several hours they will become round again. (**Key is to store dry in an OPEN container and they may take a long time to dry up depending on humidity in room).
