● Work in partners. One partner places the forearm of their non-dominant hand on the table, with their hand hanging off the edge.
● One partner should hold the ruler between the fingers of the other partner at the 0 mark.
● The partner holding the ruler drops it without any warning, and the other partner should catch the ruler as quickly as possible.
● Record the number level after the ruler has been caught - repeat at least 5 times per person.
● Find reaction times using a conversion table.
