Things You'll Need
Potato
Toothpicks
Clear glass
Container
Potting soil
Obtain a potato that has a few sprouts already growing from it. Potatoes typically grow sprouts a few weeks after you have purchased them from the store.
Insert about four toothpicks approximately 2/3 of the way up the potato; closest to the end that has the most sprouts. Insert the toothpicks evenly around the potato, almost creating a line across.
Fill a clear glass with water. Be sure the opening of the glass is large enough to accommodate the potato. Place the potato in the mouth of the glass, supported by the toothpicks around the rim, so the potato bottom is in the water.
Place the glass in a sunny windowsill and keep the glass filled with water. After a few weeks, the potato should grow shoots inside the glass. After that, a new sprout should grow out of the top of the potato.
Transplant the potato into a pot with potting soil. Carefully remove the potato from the glass and place it inside the pot without causing damage to the delicate roots. Place the pot back on the sunny window sill and water the soil when it feels dry.
Tips & Warnings
Some potatoes flower, depending on the variety.
