Description

Description

The mouth-blown glass body is filled with water until it just floats in the top of the bottle. By pressing the rubber cap, the water pressure in the bottle is increased and the air bubble smaller, the diver sinks. A closer look reveals the change in the water level in the diver. Please note that this little devil is made by hand in front of the flame. Bubbles and streaks in the glass are characteristics of handmade glass.

Delivery incl. Rubber cap / without bottle

Dimensions: approx. 6 cm

Use: 8th grade
