## Introduction: Cool Celestial Cubes: a 3d Puzzle

My friend and I needed to make a kinetic art project for our AP Physics class, and we wanted to do a 3d puzzle. Since the 50 year anniversary of the moon landing is this year, we decided to make it space themed.

## Supplies

1) Enough paper to make four of the paintings in the size you want. We made ours 45cm x 112.5cm because we were putting them on the sides of cubes that were 7.5cm on all sides. Our final puzzle was 6 cubes by 15.

2) Painting supplies

3) String

4) Hot glue

5) Cubes. We made ours out of styrofoam by cutting up large pieces with a saw. Our cubes were 7.5cm on all sides.

6) Something to suspend your puzzle from. If you had a strong ceiling, you could use that. We used an old clothes rack.

7) A way to cut up your paintings. We used an exacto knife and scissors.

8) Weights to hang on the strings to weigh them down.

## Step 1: Paint

These will be the paintings that hang on all four sides of the puzzle. We made ours 45cm x 112.5cm.

## Step 2: Cut

Now you need to cut the paintings into 7.5cm x 7.5cm squares, so you can put them on the sides of the cubes. We made a grid on the back of the paintings, and used an exacto knife and a meter stick to cut each column, then we cut the rest with scissors.

## Step 3: Thread the String Through the Cubes

We used a wooden dowel to make a hole in the middle of the cubes, then we used the back of the dowel to push the string through it. We made 6 strings of cubes, each with 15 individual cubes on them.

## Step 4: Attach the Painting

Now you need to attach all the pieces of the painting to the sides of the cubes. We used hot glue for ours, and it worked well.

## Step 6: Hang the Cubes

Now you can hang the finsished pieces wherever you are hanging them. We added 200g weights under each column of cubes to keep them from moving a lot.

## Step 7: Now You're Done!

Set this puzzle up and have fun trying to solve it!
