Help with a physics competition? Blowing in the wind?

For physics, we have a competition, as stated below, and I’ve tried so many different designs but none seem to work!! If you guys have any ideas I would love to hear them! Thanks!!
A. Objective

The objective in this event is take the air current created by a hair dryer and to design and build a device that harnesses this air current in order to lift a mass the greatest height. The hair dryer will lay on the floor and shoot the air horizontally.

B. The Apparatus

1. Teams will be given one supply of the following: 5 plastic cups, 4 paper plates, some straws, 3 pipe cleaners, two sandwich bags, 1 meter of duct tape, 1 meter of string, 3 sheets of paper, one folder, 2 note cards, and are allowed to use the physics mass sets.

2. The above supplies are the only supplies a team will get, and they are allowed to use as much or as little of these as the wish.

3. The device may be a large or small as the team desires.

4. Team may test their device as many times as they wish.

5. Nothing is allowed to touch the hair dryer.

6. No other materials besides the ones given may be used. (only one set per team!)

7. The apparatus must stay in the classroom at all times.

8. No counterbalance systems of any kind are allowed. Please check with a judge if your need clarification.

C. The competition

1. Teams will be given 2 minutes to compete in this event. The time begins once the hair dryer is turned on.

2. Teams may choose to lift any amount of mass they wish up to 200 grams total.

3. Stopping and starting the hair dryer is permitted during the two minutes.

4. The device may touch the ground during the two minutes.

5. The height reached will be measured from the bottom of the mass and will be done so by the judge.
