Items needed are:
*1 Straw that is large enough to see down the hole
*1 foot piece of string
*A weight that is heavy enough to keep your string stiff
*Scissors & Tape
Step 1: Getting Started
To get started you need to cut your string about a foot long or shorter depending on what feels more comfortable for you. Put the string through the hole of the protractor and attach it with a piece of tape.
Step 2: Attaching the Weight
Next your going to attach a small weight. I used a big paper clip as my weight. Other things you can use is a washer or anything that is heavy enough to keep your string stiff when it is dangling.
