Purchase spin art or watercolor paints and bottles with a nozzle. You’ll also need art paper, cardstock, canvas paper or board, or small painting canvases; any of these materials will do. Whether you choose to buy paper or canvas depends largely on what you decide to do with the artwork when you’re done. Buy duct tape as well.
Get a lazy Susan turntable, such as the kind that you would have in your kitchen. A lazy Susan with a 12-inch diameter that is double-tiered will work best for this. Make sure that the Susan rotates easily. Also be sure that that you won’t mind if a few paint splatters land on it.
Locate a flat, square box. Possibilities include flat gift boxes, if they’re perfectly square, or the lid of a square box, provided that it has a lip. Ideally, the sides of the box should be 3 to 4 inches tall.
Buy a piece of board that will fit the bottom of the lazy Susan. It should be slightly larger than the Susan at the bottom and about ¾ inch to 1 inch thick. You can purchase a piece like this at a home store. Many of them have scrap board for sale.
Secure the board to the bottom tier of the lazy Susan with the duct tape. This provides a sturdy base for the spinner so that it won’t tip over while you spin it.
Tape the box or box top to the top tier of the lazy Susan. Make sure that the box is situated squarely in the center of the lazy Susan. If it’s slightly off center, it will affect how the Susan spins and creates art. Additionally, ensure before each spin that the box is securely fastened to the Susan. Spinning over the course of time could loosen it.
Lay down newspapers in your work area. Spread them out quite far to catch any paint splatters. You may even want to consider working outside, if you can swing it at your school. Spin art can get messy.
Place your paper, cardstock or canvas into the box. Stick a thumbtack in the center of the paper if you’re afraid that it will slide around. However, the time that this would most commonly occur is when the lazy Susan isn’t spinning very fast. Centrifugal force will keep the paper or canvas in place when it is spinning rapidly.
Position the tube of paint close to the canvas and begin to spin the lazy Susan. This may require that one person spins while the other person squeezes the paint.
Take the artwork out of the spinner and allow to dry according to the directions on the paint bottle.
