An impossible triangle. An illusion.
Could this demonstration be the perfect analogy for human consciousness? Are our conscious experiences of the world just a trick produced by our brains?
To see how this illusion works, and see Professor Nicholas Humphrey explore the magic of consciousness, watch the full video on the Ri Channel.

So this is what happens when you mix salts of different metals (Lithium, Strontium, Sodium, Copper, and Potassium) into methanol and then light that sucker.
Pretty colours is what.
Each metal has a different configuration of electrons orbiting in the atom. When the different atoms get energy from the heat, the electrons in the different metals will be excited by a different amount. When they de-excite they release that energy as light. Different metals release different eneriges. Different energies is different colours. The more energy, the violeter the light.
Using different metal salts is also how fireworks do the thing.
See the streetlight yellow in the Sodium (Na)? Well that’s because we use sodium lamps in streetlights
