Glass Hand Boiler 16.5 x 5 cm Hand Heater of Love Made of Borosilicate Glass with Blue Liquid Scientific Decoration and Anti-Stress Gift
You already have the maximum available quantity in your cart.
The glass hand boiler is a simple yet fascinating physics toy that vividly demonstrates heat transfer. It is made of borosilicate glass and contains a coloured volatile liquid with a boiling point just above room temperature. Simply hold the bottom bulb in your palm, and the liquid will start to bubble and rise through the twisted tubes into the upper bulb. With dimensions of approximately 16.5 x 5 cm, it fits comfortably in your hand and takes up minimal space on your desk. It is suitable as a decoration for an office, children's room, or on a bookshelf.
The entire effect is powered solely by the heat transferred to the glass. The heat of the human hand warms the liquid enough for some to evaporate. The expanding steam then pushes the remaining liquid upwards through the twisted tube into the upper container, where a small level is formed. When you release the bulb, the balance between the liquid and steam is restored within a few minutes, the steam condenses again, and the liquid flows back into the bottom bulb. You can repeat the experiment over and over, observing how quickly the process starts in a warmer or cooler palm.

When handling, hold the hand boiler by the bottom bulb and treat it with care, as it is made of thin glass. Do not expose it to direct sunlight or heat sources such as radiators or hot drinks, and do not attempt to open it. If not in use, place it in a stable location where it cannot be knocked over or fall off the table. The surface can be wiped with a dry or slightly damp soft cloth. Keep it out of reach of children younger than the recommended age and always supervise play with it by an adult.
The glass hand boiler combines decorative appearance with a simple physics experiment that can be demonstrated anytime without batteries or additional equipment. It is suitable for curious children from 14 years, students, and adults who enjoy interesting items on their desks. The transparent glass with blue liquid stands out well on a shelf, by the computer, or on a windowsill. It also makes a unique small gift for birthdays, holidays, or as a token for science and technology enthusiasts. Just hold it in your hand and watch how the heat of your palm sets the liquid in motion.
