 ===== Purpose ===== ===== Purpose =====
  
 +Showing the conservation of energy, as evident in the conversion of kinetic energy into thermal energy. Often the phrase '​excess energy is dissipated as heat' can feel somewhat dismissive, this helps rectify that by showing it visually.

 ===== Setup ===== ===== Setup =====
  
 +Focus the IR camera onto the lead plate, and slam the lead ball into the plate as hard as you safely can. The point of impact should be visibly warmer in the infrared due to the conversion of kinetic energy into thermal energy.

-===== Notes =====+<WRAP center round important 60%> 
 +Lead is a toxic metal. Gloves are recommended. If you handle it bare-handed,​ wash your hands very thoroughly afterwards and avoid touching anything that may get near your mouth later on. Dermal contact is not toxic, but ingestion and inhalation most certainly is.
