Matter under the hood
Physics and Materials
These explainers turn invisible physical rules into something you can anticipate in wires, walls, and static sparks.
Best Starting Point
Start with How does static electricity work?
If you want one page that gives the cleanest first pass through physics and materials, this is the best place to begin before branching out.
A static electricity lab that lets you change humidity, rubbing, insulation, and charge leakage to see when cling stays gentle and when it jumps as a spark.

If you want the Heat transfer angle first How does insulation work?An insulation lab that lets you change thickness, trapped air, moisture, and compression to compare a lofty warm barrier with a flattened wet one.
If you want the Heat-flow lab angle first Why does metal feel cold?A touch lab that lets you change conductivity, object mass, skin contact, and insulation to compare a cold metal doorknob with friendlier-feeling materials.
