The liquid bubble timer is both a toy and a decoration. In a transparent airtight container, there are two liquids of different densities, water and some kind of oil (the oil is denser than water).
The liquid bubble timer is divided into upper and lower layers, and the two layers are connected to each other through small holes. Usually, all the oil is located in the lower layer. Just turn the liquid bubble timer over and place it. Due to the effect of gravity, the oil changes and drops drop by drop along the small holes, just like an hourglass.
Because it is also a kind of decoration, we have dozens of different shapes of oil droplets, each with its own characteristics (contact us for an electronic catalog). The interior design is also very interesting. Some oil droplets have small gears that can rotate, and the dripping oil droplets can drive the gears to rotate. Some oil droplets are decorated as the sea, the blue oil represents the ocean, and there are small sailboats inside. When the oil droplets fall, There are waves on the edge of the ocean, and the boat swaying in the waves is very dynamic.
In recent years, it has been widely used in the field of children’s concentration and treatment of ADHD.
