Dating lamp lava
Another way to stop a lava flow is to increase the lava flow's viscosity by spraying it with water, increasing the rate at which gas escapes from the flow, stirring the flow, or seeding the flow with foreign nuclei .
In Italy, engineers have installed retaining walls to try and…
The wax “lava” in lava lamps flows upward and back down because the wax and the water solution is closely balanced in density and buoyancy.
The heated wax is lighter than the saline water solution, but after cooling and contraction at the top of the lamp bottle becomes denser again.
Dip a straw one inch down into the saline solution and put a finger on the open end to hold it in place in the straw.
Drop the inch of solution into the bottle once every 10 minutes.
Let it diffuse through the bottle on its own instead of mixing it in.
Repeat until the lava first rises to the top of the bottle.
If this doesn’t suffice, move on the to the next step.
It is possible, though, to use carbon-14 dating if there are remnants of organic matter that was trapped under a lava flow. It may be possible in some special cases where the lava contains embedded organic material (plants and animals that were caught in the lava flow), or where there are significant inclusions of air (due to carbon dioxide in the air).
But the rock that makes up lava has very little carbon content, and it wouldn't necessarily be of any help in dating it anyway, since it came from underground and was only…
Two very common problems that come up with a lava lamp are cloudiness in the water and “lava” that has stopped flowing.
Fortunately, decades of trial and error since the lava lamp was invented in the ‘60’s has zeroed in on a handful of solutions that have proven successful.
