If you are looking to gross out some friends and family (and carry out serious scientific analysis at the same time) you will want to try out this bacteria growing kit. It includes everything you need to get started - you just supply water and bacteria (don't worry, it's everywhere.) This is the perfect size for science fair experiments because so many variables can be tested for bacteria growth such as:

• Is a dogs mouth cleaner than a humans mouth?
• How long do bacteria live on a surface?
• Do antibacterial soaps effectively kill bacteria?
• Where is the most bacteria in your school?
• Which door handle in the school has the most bacteria?
• Does toothpaste kill bacteria in your mouth?
• Do dark socks create more bacteria in a shoe than white socks.
• Which surface cleaner kills the most bacteria?

Our science fair kit includes:

• 6 large (10 cm wide) plastic Petri dishes
• Nutrient agar powder for creating the growth medium for the bacteria
• 6 Extra-long wooden shaft cotton swabs for collecting samples
• Beaker for preparing the agar (not shown)
• Stirring stick
• Complete instructions to carry out your experiment

In the right conditions, the bacteria usually starts growing in 4-5 days. Components are non-sterile and are not intended for medical use. For ages 8 and above with adult supervision.

Customer Feedback:
Brandon from South Carolina used this kit to test whether or not double-dipping a chip spreads bacteria. His mom, Amy, writes: "My son won 1st place overall for his school!!! He wowed the judges and now is heading to the local University for the area competition in three weeks.  I am so glad you were able to assist us. Thanks again and we look forward to working with your products in the future." Congratulations Brandon!

Yvonne in New York writes, "I wanted to e-mail to let you know how pleased we were with your product!  We purchased the Science Bob Bacteria Growing Kit Science Fair Size.  My daughters project was titled "Wash Your Hands!" and it won the 3rd grade Science Fair at her Elementary School in New York!  The directions were easy to follow & it was fun to watch the germs grow. Her project is now going to Brookhaven National Laboratory for further judging....we hope she will place in that fair as well!  Thanks again!"
