We poured enough of the mixture into the Petri dish to coat the bottom of it. For all you parents looking for educational ways to entertain your kids, there are tons of science activities that you can do at home, and it provides everything you need.įor our test, we mixed up one teaspoon of agar with three ounces of water, and boiled it for about a minute until the agar dissolved. We ordered the company’s Growing Bacteria Kit, which contains cotton swabs, six petri dishes, a plastic beaker, the nutrient agar, a shoe box, and an activity guide to help design the experiment. We decided to channel our inner 6th grader and went back to science class with the help of a Steve Spangler Science kit. The experiment: Grow bacteria in a Petri dish Tse says they haven’t been able to test the machine with the coronavirus yet because there are no samples available. Impressive.īut what about the coronavirus? Can UV-C light kill the coronavirus? In theory, yes, because UV-C did inactivate both SARS and MERS. GE is fast becoming the light of your life with more smart lighting optionsĪn independent lab tested the Coral UV using a variety of bacteria, and the results state that the device kills 99.9% of household germs. ![]() The Brava Smart Oven cooks with light (and costs about $1,000) ![]() Goodpapa is a self-sanitizing toilet brush that cleans itself with UV-C light ![]()
