E. coli vs. UV-C Showdown!: 15 seconds, 30 seconds, 1 minute, 2 minutes

In this fun & insightful science experiment, we decided to test a full-on blast of UV-C light against E. coli sample evenly distributed across a petri dish agar medium. 

We've tested the UV-C exposure against incrementally higher doses of UV-C set to 15 seconds, 30 seconds, 1 minute, and 2 minutes respectively.

You'll note that at just while 15 seconds of UV-C exposure led to limited anti-microbial sterilization, just 30 seconds already killed almost 99% of visible colonies from replicating (and thus causing potential harm).  

At 1 minute, only 2 colonies survived.

And lastly, at 2 minutes of exposure to UV-C NO growth colonies were visualized--- Wow!

Stay healthy and stay hopeful.
