A mechatronics engineer works to automate the transfer of materials and goods, and the manufacturing process. Their tasks involve identifying areas for task automation, designing, developing and testing potential mechatronic devices, and implementing design solutions.
A typical tea bag has somewhere between a gram and two grams of stuff in it. If the entire contents were nothing but fructose, and that fructose completely dissolved when you made your tea, you'd consume between 4 and 8 calories (carbohydrates contain 4 calories per gram) per cup of tea -- so that's the ceiling.
At the very least, you may singe the tea and make it bitter. At the worst, the tea bags will split or burst, creating a nasty mess. Instead, place a medium pot of water on to boil alone. Three to four cups is plenty. Once the water reaches a low boil, remove it from the heat. Place the tea bags in to steep and cover.
