Object
Construct a free-standing tower of maximum height using a single sheet of paper.

Teams
A team will consist of one to three students.

Apparatus
Each team will be supplied with one sheet of white paper (8 1/2" x 11") and one strip of heavy clear tape. Construction aids such as scissors, razor blades, and 30 cm rulers will be available for use. No other construction aids or materials can be used.

Competition Rules
1. The towers will be built from floor level, not on tables.

2. Each team must complete the construction of its tower within 45 minutes. Time will start upon receipt of the materials.

3. The sheet of paper may be cut into pieces and reassembled as desired. Parts may be rolled, folded, or slit. The paper may not be soaked, painted, or otherwise treated to add rigidity.

4. Tape is to be used to fasten parts of the tower together. It may not be used to attach the tower to the floor or any other object. Excess tape may not be used to extend the height of the tower.

5. A tower shall be declared free-standing if it remains self-supporting for more than 10 seconds (This time limit will be determined by the judge and his/her measurement.).

6. The team must inform the judge several minutes prior to the completion of their tower to allow proper time for measurement.

7. Height is determined by measuring the perpendicular distance from the highest point of the tower to the floor (Towers must be still-standing when measured).

8. Measured towers are not to be destroyed behond recognition or removed prior to the completion of the competition.

9. The highest tower will be declared the winner with the rest of the competitors ranked accordingly.

10. If a team decides to build its tower higher after being officially measured, only one additional height will be measured.


Note: Previous record height: 2.5 meters
