This item is a science kit by NanoDays.
It helps teach kids about nanotechnology in food by visualizing how the same amount of salt or sugar can cover a greater amount of taste buds using cubes.
It includes 1 tray, 16 connector cubes, a sheet of paper that illustrates the assignment, and several explanatory and instructional pamphlets in both English and Spanish.
This kit is great for any girl or boy interested in science.
It comes in very good pre-owned condition in its original box.
