  1. Open the ziplock baggie and put the SAP crystals inside.
  2. Add about a quarter cup of water. 
  3. Zip the baggie closed and let it sit for several minutes until the water is mostly absorbed. 
  4. Now add the calcium chloride to the baggie.
  5. Add about another quarter cup of water and zip the baggie closed securely. Try not to leave a lot of extra air in the baggie. 
  6. Knead the baggie until the calcium chloride is dissolved.
  7. Should feel a significant increase in temperature.
