2. Bungee Drop Elasticity Test 1 500 gram mass for elasticity test. Height measurement.

3. Bungee Drop Elasticity Test 2 500 gram mass for elasticity test with height of mass indicated.

4. Bungee Drop Elasticity Test 3 1 meter indicated and adjusted for height of 500 gram mass. 1 meter also marked on cord and measured while cord was taut but not stretched

5. Bungee Drop Elasticity Test 4 1 meter mark on cord is stretched to 1.25 meters and 500 gram mass has NOT been lifted off the floor. This cord has passed the elasticity test.

6. Bungee Drop Elasticity Test 5 Once the cord passes the elasticity test, the 1 meter mark is then stretched to the point where the cord will lift the 500 Gram mass off the floor. 500 Gram mass pictured slightly lifted off of floor.

7. Bungee Drop Elasticity Test 6 The value in meters is recorded when the 500 gram mass is lifted off the floor.
