HOME CHALLENGE: 20 Easy Experiments in 5 mins for Bored Adults and Kids at School Inside

Needle demagnatization (sp?) - the needles were too close to the lighter nozzle in the colder part of the flame. Towards the end before loosing the magnetic ability, it appears the needles were closer to the orange/yellow portion of the flame which reached demagnatization. Demonstrating this experiment is one of the many fascinating properties metal has and will continually teach even the most experienced on the subject something new throughout their life. When a 1 inch bar can be heated up in the coal forge and moved into a shape just like clay, this is why I have fallen in love with working with metal. 😁
