I'm embarrassed to admit how much time I've spent on Pinterest. The single burner did a great job of diffusing the heat across the non-stick ceramic grill plate and did a good job searing food while keeping meat juicy. For a true lava lamp effect, shine a flashlight through the bottom of the bottle. The easiest way to fix that is to use a higher concentration of alcohol (and less water), so a mixture of 91% and 70% might be helpful.

Adding the water first, then the food coloring, and finally the oil wasn't quite as fun, but it was a bit faster. Food coloring is a polar molecule because it dissolves in water. The lava” in the lamp is usually an oil, and the transparent liquid is an alcohol solution, so the two do not mix.

It is very important that you do this before pouring the wax in. If you do not, the wax will cling to the sides of the bottle and the lamp will not work properly. With the summer looming, it's time to make sure that you're ready for barbecue season and there are plenty of gas options that offer hassle free outdoor cooking.

This is my first Instructable, and I'm proud to say that I've revamped the lava lamp for DIYers- the project is designed for multiple wine bottles, so you can change the color of your lamp in just a few seconds. Harry These Dancing Unicorns Light Bottle Are Perfect For Adding.

If my memory serves me, I remember that the heavier substance in my old lava lamp solidified if allowed to completely cool (like paraffin wax, whose specific gravity varies from 0.82 - 0.96 depending on purity & temperature and starts melting at about 100°F - 37.7°C.). I don't know if this is important or not.
