The Galaxy Goose lava lamp project was finished today, and all that is left is to drop a few more drops of salt water to bring the buoyancy to the perfect level. Overview: I purchased many things from home depot throughout this past week, including multiple hose clamps, electrical tape, light bulb base, different kinds of glue, and a can of tomato paste.
After gathering all of our materials, with some help from Andrew we created our blue lava using benzol alchahol and a blue sharpie ink capsule. After squeezing out the ink from the sharpie. our lava was ready to go. Next, we poured 2 part salt water after pouring 8 parts regular water. This is where the fine tuning of buoyancy comes in. While the bottle was warm, my partner (Bijan S.) and I fine tuned our lava lamp. I enjoyed this project a lot. I learned how much benzol alchahol separates itself from water and salt water, like an oil. On a molecular level, since heat expands its only natural for our "lava" to expand and rise, but since our lamp is on the bottom of our lamp, there is little to no heat on the top. Therefore the water is colder up top, cooling our lava as it rises making it fall, and repeat. One question I had during this project was what chemicals are used for comercial lava lamps that you purchase? Are they different from the chemicals we used? In my opinion, we definitely got our desired results. A very happy Galaxy Goose If I could do this project again, I would experiment with crazy bottles. Scotch bottles, bottles from distant places, etc.
