Make a TMT Sewer

STEP 1

Stand box on its side. Cut off flaps with scissors. Cut off half the top of box. Using the photo as a guide, draw a curved line on each side of box, then cut along line. Use leftover cardboard to design the sewer’s multi-level floors, using photo as a guide.

STEP 2

Before you put floors in place, work out the position of the sewer pipes. Position toilet or paper-towel rolls in place, and trace around them with a pencil. Then cut out circles in floors.

STEP 3

In top of box (the street), position sink strainer to make main access to sewer. Trace around strainer, then cut out circle. Position strainer over the hole.

STEP 4

Tape floors in place. Then glue or tape sewer pipes in place. You can add more pipes at the bottom, if you like, so goo spills over into the sewer.

STEP 5

Let glue dry, then spray-paint inside of box silver. Work in a well-ventilated area or outside.

STEP 6

Use green and blue heavy-body acrylic paints (thicker than normal paint and more like goo) to paint the sewer as shown.

STEP 7

Draw a city skyline on a sheet of cardboard, cut out, then tape to the back of the box. Paint it blue. For extra effect, you can also tape 2mm single-link chains to the roof of the sewer.

STEP 8

Grab your action figures and start battling the enemy!
