Here is a video of a pool of corn starch on a Spanish TV show. The mixed up corn starch in a concrete mixer and then poured it into this pool. The trick is that it is a non-newtonian fluid which means that when force is applied to the liquid it exhibits properties of a solid. In the video the two hosts of the show repeatedly run over the top of the corn starch. Just to show that it is actually liquid the one host sinks into the corn starch while the other host continues to run around on top of the liquid. Near the end they have some bystanders also run over the liquid and the other host sinks into the corn starch too.
