Abstract
A stillwell/siphon system may be attached or integrated into a foam delivery bucket. When pouring foam additive into the bucket, foam/bubbles may form in the foam additive. The stillwell may fill from the bottom to prevent the foam/bubbles from getting inside the stillwell tube so one can easily ascertain the level of foam in the container. The stillwell also blocks air pockets, formed from pouring foam into the container, from entering the outlet tube, which is positioned inside the stillwell.
