How children play with it

Press the cork into the test tube, a light pressure is enough – it sits firmly. A straw is pushed through the hole, a drop of water sucked up. The cork material has a slight natural scent, the little ripples are felt under the fingers. When the stopper is pulled out again, it leaves a slight impression in the glass. Exploration is reduced to the smallest details.
