Can you build your own bridge out of blocks to span our table-top river? The key to this challenge is counterbalance - by adding more blocks at the edges you can stop your bridge crashing down in the middle.
Test out your circuit-building knowledge with this series of electrical challenges. Can you turn the lights on, construct a hand dryer or even wire a burglar alarm?
At Energy Store you do the hard work, pumping water to a tank high above your head. As the water flows back down, it turns a turbine to make electricity. Can you generate enough power to turn on a TV?
Heave on a rope to lift a heavy bowling ball, then let it drop back down. As the bowling ball falls it forces air through a narrow tube, sending a small ball at the other end rocketing into the air.
Have a go at building Launchpad's Arch Bridge. Even without glue or screws the Arch Bridge is strong enough to support you and your friends, so build it then test its strength.
How does a liquid's viscosity (or runniness) affect how it drips, pours or even spins? Compare three liquids to find out for yourself at this collection of sticky exhibits.
In Launchpad we've got a wall which can freeze your shadow - strike a pose, wait for the flash, then turn around to see your shadow trapped on the wall. What's the weirdest shadow you can make?
You can't see sound, but you can play with its effects at Sound Patterns. Adjust the sound to find the frequencies that will make the water in the tube jump and dance around.
See the world differently with our Thermal Imaging Camera, which detects heat rather than light. Which bit of you will appear hottest on the screen?
At Icy Bodies watch carbon dioxide turn straight from a solid into a gas, creating swirling misty patterns as the solid pellets ricochet across the surface of a pool of water.
