Sarvar; The fountain of youth [Edit]

In the movie Cocoon from 1985 a group of seniors find themselves energized with youthful vigour when they swim in a pool containing alien cocoons.
In Sarvar, Hungary, the aliens didn’t arrive yet but there is a source of thermal waters with crystals that cures old age problems and revitalizes life. Because Sarvar and Hungary are not so near, a man had the brilliant idea of packing and distributing this water. But there is much more. This water was a success and they could finance an ad that was aired on the Hungarian TV in the 80s. In this ad you can watch very old people full of energy and hyperactivity. The end of the ad turns it into a delightful TV spot.
