This is a Nano Food science kit by NanoDays.
The kit helps teach children about nanotechnology in food by visualizing how the same amount of salt or sugar can cover a greater amount of taste buds using cubes.
This kit 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.
It comes in very good pre-owned condition in its original box.
