Does anyone know the process of how these are manufactured? I already know the materials.

Don’t have any idea but my grandsons loved watching them get bigger in the water….they played with them inside and outside!

Do these go back to the original size when they dry out

Yes they’ll eventually shrink and dry back down

How long do they take to grow?

You must wait a full 3 days for them to get larger. It’s exciting to see them get larger. My grandson could not wait, so in 2 days the were slightly larger & he was so excited.
