This is possibly my favourite number trick! You receive four coloured sticks with numbers around them.
Spectators can arrange them with ANY sides facing up (all sides are different) and with the sticks in ANY order to make a series of four, 4-digit numbers.
Instantly you can name the total, long before they can do so with a calculator!
What’s more, you can repeat this and the total will be completely different each time, yet you are able to state the total immediately!
