Capped dice Nuclear Decay Experiment

A cap-able set of dice to simulate random nuclear decay! Each dice represents a single atom which can undergo nuclear fission or fusion. Whenever you spin the dice, it represents one year going by and the atom having a random chance of decaying.  

Experiment Procedure:

1. Set your nuclear decay constant (λ) to a number from 1 to 6
2. Open all the dice caps & spin the dice
3. If the number on the dice is smaller or equal to λ, close the cap
4. Count the number of dice left & document them on a table
5. Repeat steps 2 to 4 to simulate atoms randomly and spontaneously decaying!

* Works best with more than 10 dice

Here is an example result using 100 dice, λ = 2
