How does water affect the speed of the goo?

We think that if you put water on the Saran Wrap, the goo will go down the chute faster.

 (2) Half bottles of a 2 liter soda bottle-32 cm.  (1) Half of a Quaker Oats bottle-23.5 cm.  (1) Cardboard box  Duct Tape  Saran Wrap  Water

Step 1- Gather all materials. Step 2-Cut all of the bottles. Step 3- Duct tape all 3 bottles together (vertical). Step 4- Put Saran Wrap over the chute. Step 5- Use the other half of the Quaker Oats bottle and duct tape at the top of the chute. Step 6- Cut the box so you have a base. Step 7- Cut a semi-circle in the center of the base. Step 8- Tape the Quaker Oats bottle to the semi-circle.

Our variable was water.

Before we put water on the Saran Wrap, the goo took 34 minutes and 41 seconds to go down the chute. After we put water on the Saran Wrap, the goo took 23 seconds to go down the chute.

In conclusion, our hypothesis was correct. If you add water to the Saran Wrap, the glacier goo will go down the chute faster.
