Answers to Make-To-Learn Q's:
1. What did you make?
I made a working, permanent lava lamp and the materials for it are on the next page. Also, on my website, I show instructions for other not permanant lava lamps.
2. How did you make it?
I got the idea for this project from when I was talking to my science teacher for science fair project ideas. I did not work with anyone else and my plans changed when I poured the ingredients in too fast and had to restart. That was a disappointing setback that I had to improvise/fix, but, in the end, it turned out much better the second time and it was a good learning experience.
3. Where did you make it?
I worked on it at home, but did a few small research things at school. This project connected to other parts of my life because we had been learning about convection currents in science and this helped me understand the concept better and get an A in that chapter.
5. What did you learn?
My biggest problem was that I had poured the ingredients in too fast on my first trial. Then, I had to figure out what I did wrong and why the solution got very foggy. Eventually, I problem solved and figured it out. I am definitely proudest that the lava bubbles got so big and moved so much! I was so excited that I was really able to do it and accomplish my goal. I feel that that was a good life lesson to learn is failing and then getting back up and succeeding! It felt great. If I were to do it again, I would definitely not pour so fast so that my first try would be correct. Also, I would've added more 70% in the beginning so that I didn't have to do it again at the end to balance out the density mix of the formula.
Please know that this project will not be cheap and also is trial and error sometimes and you must have patience. It was a great learning experience and I am sure it will for you too. I am going to be teaching you how to make a permanent lamp and will not be using Alka-Seltzer, although, NEVER leave the lamp on too long because you will be using a glass mason jar. Please look at my website for more details of this project: http://lavalamps.webs.com
Step 1: Step One: Materials
1 large mason jar
2 four ounce bottles of mineral oil
3 sixteen fluid ounce bottles of 70% isopropyl alcohol
2 sixteen fluid ounce bottles of 91% (or 90%) isopropyl alcohol
1 40W light bulb
1 60W light bulb (optional)
1 light bulb stand (as shown in picture)
1 light bulb stand cord (make sure it connects to the stand)
1 large aluminum bowl
Step 2: Cut the Hole in the Bowl
Step 3: The Formula
You need to make sure that you follow the steps very closely.
Throughout this step, you MUST POUR EVERYTHING SLOWLY.
And by slowly I mean REALLY SLOW.
If you go to fast at all, huge bubbles will plunge in the bottom and will make your lamp foggy.
Anyway, first you fill the jar 1/4 full with mineral oil. (You do not have to pour the first ingredient slowly though… )
After that, fill the jar another 1/4 full with 91% (or 90%) isopropyl alcohol.
Then, you can finally fill the rest of the jar nearing the top with 70% isopropyl alcohol.
Close the lid and ensure it is sealed.
Finally, you can put the formula on the top of the bowl and put the light under it (make sure light is plugged in).
*If you do not see any movement of bubbles after an hour, then you can add more 70% isopropyl alcohol to your discretion. This is why I believe you should leave some space in between the top and the formula before you put the formula all together on the bowl.
