The reaction between ammonium thiocyanate and barium hydroxide octahydrate is endothermic. It absorbs heat from the surroundings. As a result, the temperature of this reaction will drop quickly. This causes the beaker used to freeze to the wooden board. In this video, the beaker was able to hold approximately 9kg.

Amazing Presentation
The thermometer is great, but the freezing provides the "WOW" factor.
