In the video, a person is seen putting their hand into a bowl filled with a blue substance. The substance appears to be some kind of slime or gel that is very thick and sticky. The person then proceeds to pick up a handful of the substance and squeeze it, causing it to stretch and change shape. The substance has a shiny and glossy texture, and it seems to be quite malleable. The person continues to play with the substance, stretching and squeezing it, and it appears to be quite satisfying to watch.
