## Mechanics

 Bermuda Triangle

Artificial Gravity Pendulum
Simulates the effect that different gravity strengths (Moon, Jupiter and the Earth) have on the pendulum's rate of swing.

Balancing the Palette
A palette is made to balance on a ball by moving weights on its surface. It acts like two-dimensional scales.

Bermuda Triangle
A boat floats in a tank of water until air bubbles are introduced into the tank and it sinks.

Bouncing Balls
Combinations of different balls can be dropped together down wires. The sometimes startling result helps us to visualise physical processes occurring in the explosion of supernovas!

Cartesian Diver
A tube floats in a closed tank of water. As the pressure in the tube is increased by squeezing a tube, the floating tube sinks. This is the diver.

Coupled Pendulums
Shows the transfer of energy between two identical linked pendulums.

Curved Water
A thin container of water spins to display the curve of the spinning water surface.

Enigma Scales
These scales do not work as you might expect - but demonstrate how practical scales are best constructed.

Gallileo's Pendulum
How does the length of a pendulum affect the rate at which it swings?

 Gyroscope Chair

Gyroscope Chair
Demonstrates gyroscopic forces at work.

Hydraulic Lift
A visitor is lifted by the pressure from a head of water. The head arises when a container of water is lifted with a winch.

Hydraulics
A hydraulic tug of war. Visitors can pull on pistons, connected by hydraulic fluid. As the pistons are different sizes, the forces are not equal on each side.

Just Scales
Experiment with a balance to find out how simple scales work.

Momentum Platform
Like an ice-skater you speed up when your weight is near the centre of rotation. This shows conservation of angular momentum.

Money Spinner
Coins spin around this horn-shaped well, getting faster as the radius of their orbit decreases.

Puck Race
Compare how things slide on surfaces of different friction.

Puck Table
Investigate motion when friction is reduced on this air table.

Pulleys
Find out about pulleys - and whether more or fewer pulley wheels make it easier to lift a heavy weight.

Weight/Mass Pendulum
Does the mass of a pendulum affect the time of swing?
