We ordered sterile petri dishes, liquid nutrient agar, and sterile swabs from HomeScienceTools.com (Definitely bookmark worthy, by the way!).
|The gloves were more for effect - they aren't sterile - but don't they look scientific?|
|The potholder is not for effect - that bottle was hot!|
1. Liquid Nutrient Agar is well worth purchasing. Although slightly more expensive - it is already sterile and only requires heat to liquefy. Powdered Nutrient Agar requires addition of distilled water and boiling to sterilize.
2. Open the petri dish as little as possible when pouring the agar in to avoid contamination.
