Wire shopping carts are a common sight in grocery stores and other retail establishments, but they can be a nuisance to push around. One way to make them more manageable is to hit them with a wire. This will cause the cart to roll more smoothly and easily.
To hit a cart with a wire, simply find a wire that is long enough to reach from the ground to the top of the cart. Then, hold the wire in one hand and use your other hand to hit the cart with the wire. Be sure to hit the cart hard enough to make the wheels spin, but not so hard that you damage the cart.
