Angel Ayala touches a replica of a vessel during the classroom segment of a special tour at the Penn Museum in Philadelphia, Nov. 25, 2013.

Ayala, 16 and blind since birth, touched ancient Egyptian artifacts at the University of Pennsylvania archaeology museum as part of a special tour for the blind and visually impaired.

The museum began offering the tours in 2012 as part of an initiative to make their extensive collection more accessible.

"When I touch things, it's my version of a sighted person's eyes. It tells me way more than a person describing it would ever," Ayala said.

Most major U.S. metro areas have at least one museum that offers some type of hands-on experience, from touching objects with bare hands or gloves to feeling replicas, according to Art Beyond Sight, a group that makes visual culture accessible to the blind and visually impaired.

Students sanitized their hands before feeling the pieces, which were pre-selected by conservators. Though thousands of years old, the artifacts shouldn't be damaged by clean fingers and a light touch, according to museum program coordinator Trish Maunder.

Overall, the museum is engaging with nearly 250 blind or visually impaired people this fall, up about 32 percent from last year, Maunder said. Educators are already planning next season's curriculum on ancient Rome.
