Twin boys learning and having fun lifting themselves on an interactive in Sir Issac's Loft

Sir Isaac's Loft

Enter the playground of experimentation and discover falling objects, chain reactions, and optical illusions that bring Newton's laws to life. Pulleys, prisms, and pendulums captivate the mind and illuminate classic scientific principles. How does different lighting affect our perception of the world? How do energy and motion transfer when two objects collide? Build a domino maze and create a chain reaction by toppling them over. Gaze at optical illusions guaranteed to make you think your eyes are playing tricks on you. And don’t miss the centerpiece of this exhibit— a George Rhoads kinetic sculpture that uses 18 smaller devices to circulate dozens of acrylic and golf balls.
