What is the lava lamp?
Traditional lava lamp consists of a conical metal base, which contains a 40 watt bulb, and a glass container in the shape of a tears that comfortably suits the base and bulb. Inside this glass container is a combination of colored water or alcohol and a lighthouse consisting mainly of paraffin wax, carbon tetrachloride and mineral oil. When the bulb warms the bottom of the glass vessel, the colored goo slowly rises in a way that indicates the lava flow.
Lava lamp is much more decorative than functional. 40 Watt bulb illuminates lava goo and liquid, but not anything else. One could consider the lava lamp as a stylish night light, but long -term use is not recommended. As the lava lamp grows warmer, the individual pieces of lava goo tend to become frenetic droplets instead of a pleasing display with slow movement.
Some sources say thisThe MPa was patented in England in 1963, although the chemical GOO formula was noticeably "humid" because it did not include paraffin wax that gives the lava its weak flow. The American patent in 1971 describes the formula that is still used to this day. Lava lamp works on the principle that oil and water do not mix. When the greasy and wax lava base melts from the heat of the bulb, the resulting convective currents drive Goo up. Because wax and oil cannot mix with surrounding water or alcohol, goo holds in large droplets.
When the "lava" in the lava lamp cools, it returns to the bottom. Once the lava lamp is completely turned off, the wax solidifies and catches the mineral oil. Water or alcohol remains clean because none of the ingredients has ever mixed with it. In the books of scientific experiments and on the Internet are available recipes for home lava lama. Most of them include a combination of candles and mineral oils in the form of carbon tetrachloride available at the local cleaner shop. GlassThe DNA is filled with either colored water or a mixture of alcohols.
Household decorators at the beginning of the 70th years considered the lamp a suitable accent in a modern lair or in the living room, along with other "mod" devices such as sound organs and posters of daily glo with black lighting. Modern lava lamp enthusiasts tend to buy them for their kitschy or retro feeling. Monitoring the lava lamp during slow movement can be very relaxing. In each lava lamp there is also a small scientific lesson about emulsions and specific weights, but above all offer a sense of whim that is generally not in other lighting accessories.
