Students from the Rhode Island School for the Deaf helped make a video of a popular song in American Sign Language. Four students from the school attended deaf film camp in the Adirondacks near Old Forge, New York.

The students helped sign Pharrell Williams' song "Happy." The kids from our area who were involved are 14-year-old Cole Evaristo of Dartmouth, Mario Pacheco, 14, of Providence, Alize Pabon, 15, of{} Pawtucket and 13-year-old Chelsea Gonzalez of Warwick.

The songwriter, Pharrell Williams, even tweeted a "Thank You" to the camp for making the sign language version.
