This is not water, but something like salt water or jelly.

Due to the high concentration of brine or the addition of gel components, the intermolecular force of water itself increases, making "water" maintain a relatively fixed shape in a short time.

Simply from the appearance, as long as the added gel or salt is kept in a certain concentration range, the appearance can be guaranteed to be very similar to that of water, and it can also look like "keeping the cup shape on the table for a few seconds before the water overflows".
