Grafton – On Tuesday, Jan. 14 Keith Johnson captivated the students of South Grafton Elementary School with bubbles. Johnson discussed the scientific process of how enormous and detailed bubbles are made while making the bubbles. The students were amazed, whether he was making bubble sculptures of snow people and flying saucers or placing a student inside a large bubble. He taught them how and why a bubble can last in a jar for 340 days. The program was funded by South Grafton-PTO.
