Siphox is a great platform
Siphox is a great platform, easy to understand explanations of topics that you would need a medical degree or at some medical training to absorb. The only thing that didn't work for me in two separate tests was the heating pad. First one didn't have the metal circle thing in it, the second had one but it just didn't work and didn't cause the chemical reaction needed to heat the liquid. Not a big deal though in my estimation.
