The 2 garden pots are labeled as “Water” and “Milk”. Each of the 2 pots is filled with the same amount of soil. Poke 10 holes in the soil in each of the pots (about an inch deep) and place 10 tomato seeds in each of the 2 pots. Cover the holes with soil. Additional seeds may be planted in case some of the seeds do not germinate. The extra plants can be removed later.
