Compressed air is blown at high speed through the hose, creating a low-pressure zone inside (Bernoulli’s principle). This low pressure sucks the liquid out of the upper container and carries it down into the bottle, a classic Venturi/Bernoulli effect demo.

Spray marker works by mechanically propelling fine marking powder through a thin needle tip. It has a small reservoir of fluorescent green powder. A spring-loaded plunger (visible in the later frames as the translucent plastic piece with fins) is cocked and then released. When triggered, the plunger rapidly compresses and forces a burst of powder out through the extended metal needle nozzle, creating a directed spray that can reach the bottom of deep holes. This lets you mark the exact depth or center of drilled holes in wood, masonry, or metal without the powder scattering on the surface. The needle tip is designed to fit inside narrow holes, and the powder sticks to the target area for a clear, visible mark.

Fill-level indicator for gas cylinders. It sticks magnetically to common steel propane or butane bottles and uses ultrasound to check whether liquid gas is present at that height. Green means gas is still there; red means the liquid level is already below the sensor. You slide it up and down the bottle to find the fill line.
