It's great when new experiments give us terrific data. It's even more rewarding when we overcome some initial failures. "Figuring it out" never gets old!!! #TheJourneyIsEverything #FromIdea2Reality #StillHavingFunInYear31

Kicked off the new year by discovering water under our kitchen sink. Found source of the leak. Quick phone call to my Dad, $6 trip to Lowes, and we are dry! #LittleVictories #BrackenFamilyFun

Flame tests! Switched from test tubes & nichrome wires to 12-well plates & Q-tips. Excellent results. No more labeling test tubes, need 3 mL of each solution per lab station.
