Awesome!

My son did a science project of bacteria growth on toothbrushes that was kept in different areas. When it was time to swab the brushes for tesing bacteria to grow in dishes, I crossed my fingers. Two days passed with no growth just like expected but by the third day it was amazing to see the growth. At the end of our growth period the whole family was amazed at the results in the dishes. This kit was very easy and the instruction book is filled with great info and easy to follow directions. I will definatly buy this product again.

Great for Science Fair

I used this product with my 8 year old son. We had wonderful results sampling his Dad's shoes and our dog's paws (the shoes grew many more microbes). My son was able to dip a q-tip in the nutrient solution (a small bottle), swap the sample, redip the q-tip and then pour the solution into the petri dish. Parent supervision is required - we are not sure what the nutrient solution is and he needed some help so the dishes didn't spill before the solution gelled. Also, we are not sure what kinds of microbes grew or how harmful they might be. I taped them shut but they should not be played with or carried around the house. And I washed our very cooperative dog's feet. It took three or four days before visible microbe colonies showed up so there was some anxiety. But after that, the microbe colonies prospered. We had a control sample (nothing swabbed but still dipped the q-tip in the bottle) and it didn't grow bacteria. You can buy petri dishes for very little money and make your own nutrient but for an elementary school student (and his non-scientist mom), this was perfect.

We took pictures of the microbe colonies in the dishes and used them on his board because the school didn't want the microbes at the fair!
