Coins are used every now and then, and they can always be found at unexpected places at home or any other places. Therefore, it could be better if the coins can be collected in time. This cap can be placed directly onto a normal beverage bottle, and coins can go through it from the top and side. The inspiration of the shape came from the logo of our campus (Nottingham), which is a tower of a castle.
