+### 1. Make your maracas
+
+Cut 2 short lengths of drinking straw for your maraca handles. 
+Using Sugru (or other modelling material), make 2 maraca heads by rolling it up into balls.
+Push the maraca heads onto the straws and mold into a maraca shape.
+Connect lengths of wire to the connectors of the 2 tilt sensors and then push each sensor into a straw until it presses into the Sugru.
+Leave the Sugru to set.
