I am making a drinking apparatus for a party. I have punch in a bowl. It is siphoned from there through a small rubber hose. That hose drains into a glass beaker with a burret on the bottom that the kids can turn on and off to get the punch out of the beaker. The problem is that the punch fills up the beaker and doesnt stop. HOW do i make it stop and fill up only part of the beaker? Any ideas please help!
