| power of water. | | | | farther or more arced? Did the lower or higher holes |
| Get the following materials before you start the | | | | seem to produce the streams of water that pushed |
| project. | | | | out the farthest? |
| - A half gallon orange juice or milk carton | | | | 7. Make notes on your graph paper. |
| - An ice pick or a nail about the size of an ice pick | | | | 8. Now using new tape tear 4 pieces an place a piece |
| - Tape preferably masking tape | | | | over each individual hole. |
| - Water | | | | 9. Refill the carton and place it again on the side of the |
| - A sink (no you won't need to go get one but you will | | | | sink. Take off the bottom tape and note how far the |
| need to have a sink available to do the project) | | | | stream pushes out. Measure it. Put your finger on the |
| - Scissors | | | | hole and replace the tape. Now take the tap off the |
| - A Permanent market or pen | | | | second hole and do the same thing. Refill the carton |
| - Paper | | | | with more water and do the 3rd hole and finally the |
| - A ruler or tape measure | | | | last one making sure to refill the carton before testing. |

| this on all sides. Now using the scissors cut around the | | | | think about a pyramid of cheerleaders. The |
