This book provides a range of easy-to-do magic tricks based on Chemistry, Physics, Engineering and Mathematics.
The video features Richard Garriott on Science and Magic and shows how the properties of ferofluid can exploited to create a magic trick.
A video is shown of a square with its diagonals marked. The resulting regions are, of course, 25% of the whole square. A motion graphic shows one of the diagonals sliding down a side to rest at the mid-point. What percentage of the whole is each region?
This is an adaptation of a print-based task designed by...
A stack of cups is shown. Cups are added to the stack. There is a variation in the rate at which cups are added. The challenge is to graph the weight of the stack of cups against time.
Weight of stack 2 video
A stack of cups is shown. Cups are added to the stack. Part way through a different style of cups is added, before the cups revert to the original style. The challenge is to graph the weight of the stack of cups against time.

The video shows a deck of cards being dealt between four people. The cards are handed out at a constant rate. The challenge is to graph the number of cards per person (‘size of hand’) against time.

A stack of cups is shown. Cups are then added to the stack. Part way through the rate at which cups are added is increased. The challenge is to graph the height of the stack against time.

A set of weighting scales is shown with a stack of cups on the scale. The cups are removed one by one in a fluid movement. The task is to graph the weight on the scales against time.

A person is shown spinning around on a playground ‘carousel’ before getting off and walking away. The task is to graph the distance of the person from the centre of the carousel against time. Whilst the person is spinning on the carousel the resulting graph shows that distance is constant. This story can be used as...
The initial frame of the video shows a toy pony. As time progresses additional ponies are added to the scene. At the end, all of the ponies are taken away. The challenge is to graph the number of ponies in the frame against time. The resulting graph is one with discontinuities.

A paper plane is thrown from the balcony of a house. The plane initially gains height before curving as it falls to the ground. The challenge is to graph the elevation of the plane against time. The resulting graph is non-linear.
