How to Make a Styrofoam Colosseum

The Roman Colosseum has weathered over 2,000 years of the worst weather and harshest conditions that the earth could throw at it and it still stands as a feat of engineering today. It was originally built in the first century B.C. to host gladiator competitions, hunts and other national events.

Now, it is a huge tourist attraction for people around the world. If you are not able to purchase a ticket to Rome any time soon, don't worry. You can make an impressive model of the Colosseum yourself--out of styrofoam.

Draw a 7-inch circle in the centre of each round styrofoam disk with the black marker. Use the styrofoam cutter to cut out the 7-inch circles from each disk, turning each disk into a hollow hoop.

Draw several 4-inch tall, 3-inch wide arches on the styrofoam sheets. Draw as many as you can fit on each sheet. Cut these arches out of the styrofoam sheet. You should be able to get at least 24 arches from each sheet.

Place one of the hollow disks down flat on a work surface. Glue the arches to the styrofoam disk all around so that you completely cover the disk.

Glue the second disk to the top of the arches on the first disk. Repeat the gluing of arches onto the disk in the same manner as the previous steps.

Repeat the stacking and gluing with the remaining two disks and arches to create a four-level Colosseum.
