Special Status Update: We have cancelled all scheduled Sleepovers. We will be providing full refunds and waiving any administrative fees.


A Sleepover at the Science Centre is a great group event, an unforgettable family outing and a unique indoor camping experience. For over two decades, we have planned fun-filled, action-packed nights of science after dark. Our sleepovers have taken you underwater, up to outer space, into the laboratories, and much more.

2020 Theme: Mind Matters
Spend a night at the Science Centre and uncover the remarkable power of your mind! Experience why you think, feel, and react the way you do with fun games, optical illusions and brain teasers. Train your brain with our interactive exhibits, then dance up a storm at our DJ–PJ dance party before it’s time to give your mind (and body) a rest.
