Pump for little pieces of paper Answered
Hi, I'm going to make a display cabinet for an art project. Please see image for more info. The idea is to have a container (gray box) with ash on the back side of this cabinet, then there should be a pump (red dot) emptying this container and blowing the ash to the front true a tube (see red line) into a double glass window.
How can I create something like this? the problem is the transfering of the ash (little pieces of paper) from the back to the front.
