Comments: The blow gun is a long metal tube with a tubing connected on one end and a trigger on the other end. Aim the blow gun by looking down the barrel. The trigger is wired to the electromagnet so that when the marble shoots out of the blow gun the connection between the battery and the electromagnet is broken. The electromagent is a reasonable magnet for a while after the current is cut as well, so it is necessary to weigh the monkey.
