11. Create an Infinite Source of Onions
Supplies required: onions
Making Cost: $1–$3*
Because they are a vegetable that practically gives itself away, onions are fascinating. Seeds or onion kits can be used to cultivate onions. You may be surprised to learn that if you leave a grown onion in the ground throughout the winter rather than picking it, it will start to grow more.

Like garlic gloves, the onion creates parts that may be dug up, separated, and replanted in the spring. You’ll have an unending supply of onions come springtime if you leave a bunch of mature onions in the ground during the winter.
