Crayola Airbrush Window Marker Craft & Activity Set

I use this kit to use markers for an airbrushed effect. The kit includes an air pumper. You just attach the marker to the pump nozzle and pump the handle 15 or so times. Then pull the lever and the spray comes out like an airbrush. It seemed to drip a little with some of the markers but if I dried it out on the inside of the nozzle, it seemed to help a lot. I used a paper towel to do that. Also don't spray too much onto the stencil or the finished design didn't look as good. Especially with the special window markers that the kit came with. It seemed to drip easily on the window if too much was sprayed. But other than that, it looked really cool on the window.
