bubbles. So that’s why we call it a lava lamp inside of bottle. The conclusion is that you can make lava lamp household items if you use Alka-Seltzer‚ water‚ food coloring‚ and vegetable oil. So if you want to try just do what we did. That is our experiment. Why this happened because the Alka-seltzer had a chemical reaction beacuse of some powder on the outside of the alka-seltzer so the bubbles carried the food coloring up to the top of the bottle

Introduction The purpose of this experiment is to validate the effectiveness of different types of disinfectants and antibiotics on microbes. It was hypothesized that antibiotic products work better than regular products such as soap‚ hand sanitizer etc. According to the handout that was provided in this laboratory work‚ it was believed that many of the environs occupied by individuals are exposed to different types of microbes and methods of eradicating such microbes has been studied over the years

people brings in a monarch once more. It is recommended that the theory of the separation of powers grew out of the older theory of mixed monarchy as expressed by the Greek historian of Rome Polybius whose idea was simple.
