Disclosed is a dispensing system a dispenser having a first chamber containing a first material and a second chamber containing a second material. The dispenser is configured to selectively retract one of the chambers at least partially within the other to transition the dispenser between an extended position and a compact position. The first chamber includes an open top end that is, before use, covered with a first breakable membrane. A breaker ring, at least initially covered with a second breakable membrane, is configured to break the breakable membranes when the dispenser is transitioned between an extended position and a compact position. In the compact position, with the membranes broken, the first material and second material are free to form a mixture that can be dispensed via an opening in the dispenser's openable tip.
