The present invention is directed to a magnetic drinking cup, which is a drinking cup containing magnetic and metal components. The magnetic and metal components allow for a tight seal and decrease the opportunity for bacteria and mold to flourish. Many cups known in the prior art have screw top lids, which have tight and narrow crevices making the cleaning process cumbersome. If not cleaned immediately after use, it becomes challenging to remove the debris remaining in the cup, and around the inside of the lid. These small areas create a trap for bacteria and mold, if not cleaned properly. The same issues can arise with reusable straws. There are not many tools on the market that can clean a straw thoroughly from top to bottom. If not all contents are removed from the straw, it becomes a petri dish of bacteria, and if moisture remains, then mold will have the ability to grow. This invention allows for cleaning ease, and provides fewer areas where bacteria and mold can flourish due to a magnetic seal instead of a screw top seal. Further, the drinking cup can be replaced with any storage container, including children's “sippy cups”, Tupperware, or any food storage container that requires a tight seal.
