Boog / coffee warmer


A cup of coffee often gets cold before you finish it. BOOG heats up your cold coffee. Pull the green part on the top of the handle. This simple movement will mix the water and calcium chloride, which was stored separately inside. They will turn into calcium hydroxide and emits enough heat to warm up the coffee to around 80-90 degrees Celsius. Now you can enjoy hot drink anywhere, any time.
