# Why are the walls cornstarch beads, not salt brick?

## Answer

The walls and ceiling are hand-placed non-toxic cornstarch beads, not Himalayan tile. Daniel’s build is nicknamed “a million touches.” The site also calls it an accidental world-record bead installation by one person in about 600 hours.

The beads are not only an aesthetic. They drink sound, so the cave is quiet without stuffing a breathing room with synthetic foam. Guests and reviews compare the hush to a float tank, though this is not a float tank.

You came to rest and breathe. Echo would fight that. Pink brick would be a different chemical and a different sound. The beads are the house’s answer to both.

The site’s own wording is “largest bead installation by a single individual in the shortest time (600 hours).” A Guinness listing is not on the public pages.
