The Ultimate Space Cup (USC) can turn your drink hot or cold. The airtight tubes along the outside of the cup holds liquid nitrogen to cool your drink. To turn the content hot, simply remove the tubes and shake the cup. The red balls attached in the middle of the two rings will trigger a chemical reaction heating up the drink. Two pouches on the sides hold water and flavored powder. Press the pouches and the content will empty out from the orange openings to form your drink. The pouch are removable for accessing different flavored drinks. The lid prevents the liquid from floating out. A little key-shaped insert on the straw serves as a trapdoor to let you sip the drink or to stop it. To prevent the cup itself floating around, magnets are installed on the bottom of the USC. This is the only cup you will need in space! Thank You!
