Today, 5th of July, is LGBT in STEM day (STEM meaning science, technology, engineering and mathematics). A good way to celebrate is watching a video by doctor Lana Vuli, the science queen.
In this video, Lana adapts my post about the real neutral pH with an LGBT twist. The tag on your shower gel might be lying about the neutral pH and she will show you as nobody has before.
As usual, subtitles are available in English, Catalan and Spanish.
