KANSAS CITY, Mo. -- A child destroyed a one-of-a-kind piece of artwork at Kansas City's Union Station, and it was caught on tape.

Tibetan monks had been creating the sand art, which looks like a colorful tapestry on the floor, for two days.

A surveillance camera recorded a young boy, possibly a toddler, who walked into the sand and started dancing, while his mother mailed a package at the post office. After a few minutes, the video showed a woman pull the child away.

"Never happened before, never happened before like that," monk Jampa Tenzin said.

The monks said they were not angry at the child or his mother. Instead, they've been hard at work to finish the piece.

The monks are on a yearlong tour of the United States and Canada to raise money for their monastery. The original monastery in Tibet was destroyed. They were about halfway finished when they left for the day Tuesday, roping off the artwork before they left.

The lead monk said it was "no problem," adding, "we will have to work harder" to get it finished before Saturday. It will then be swept up and offered to onlookers for their gardens. The rest will be placed in the Missouri River.
