Abstract: The ICE-TRAP is an invention that makes the drinking process a much more enjoyable and profitable experience. This is because the ICE-TRAP adds quality to existing drinking products, while at the same time making them more efficient for the consumer and the producer. The effectiveness of the ice trap can be seen not only in its design but also in the simplicity of the principles the ICE-TRAP is based on. Ice floats in liquid because of its density, ice cools the liquid, liquid comes through the end of the straw. The ICE-TRAP utilizes the buoyancy of the ice to trap it at the end of the straw where the liquid flows through. The effect of this product will be seen in the fact that drinks will last for a longer period of time, people will not have to sacrifice their drink with too much ice. And the temperature of their drink will be much cooler for a longer period of time.
