How to Freeze a beaker to wood

Chemistry can be very fun when you create different kinds of reactions between elements. Note that caution should be employed to not harm yourself while performing these reactions. Ammonium Tricynate reacts with barium hydroxide octahydrate in endothermic form. Endothermic reactions are those which absorb heat from the surroundings during the reactions as opposed to exothermic reactions which produce a lot of heat during the reaction. When endothermic reaction occurs, depending up on the intensity of the reaction temperature can drop very quickly. So when trying this reaction on a wooden board, you can freeze the board quickly as shown in the video. This video shows how to cool a wooden board quickly by performing an endothermic reaction on it.
