In keeping with the science theme of Summer Reading this year at the Princeton Public Library, three children’s programs will be held in the Community Room.

On Wednesday, July 16 at 2 p.m., Piccirillo Sciencetelling presents “Potions,” using science experiments with dry ice and imagination to tell the story of a hidden underground laboratory and the ferocious guard determined to protect its mysteries forever. Children will discover the secrets of the laboratory while they learn about the concept of matter, its three states, and how to change it from one state to another.

“Sweet Science: Experiment with Candy” is the title of the program on Monday, July 21 at 4 p.m. Children five and older can test, soak, stretch, dissolve, smash — and maybe even taste — candy to learn more about science and the world around them in this fun and educational session.

The program on Wednesday, Aug. 6 at 3 p.m. is “The Science of Giant Animals.” Bill Bosenberg of Snakes-n-Scales returns to the library here, this time with some giant animals.

The library is at 65 Witherspoon Street. Call (609) 924-9529 or visit www.princetonlibrary.org for information.
