Prepare Caulking Tube for Use

What happens here

To prepare the caulking tube for use, the presenter pulls off a small tab from the nozzle. He then screws down the cap, which activates the tube by puncturing an internal seal, causing the caulk to begin extruding from the tip. He also highlights a small sealing plug attached to the pull tab, designed to reseal the tube for future use.

Goal: The presenter demonstrates how to prepare one of the reusable caulking tubes by removing a pull tab and screwing down a cap to puncture the seal, allowing caulk to flow.
