What inspired me?

Well, I love obscure, weird and impractical materials such as concrete while incorporating the material into a project where its features, properties and function isn't required. I love concrete as its such an industrial material and has a very smooth finish.

What will you need?

- Compass

- Pencil

- Ruler

- Scissors

- Duplex board

- Concrete or cement mix

- Water

- Mixing bucket

Step 1: Step 1: Making the Mould

The mould is very simple. Grab your duplex board and turn it over such that the grey part is facing up. Draw a circle that has a radius of between 40 and 80mm. When this is done, draw another circle that is about 40mm bigger then the first.

When this is done, work out the title circumstances. You can do this by completing the equation pi x Diameter =circumference. When thus is done, add 50mm and then mark it out onto a strip of duplex. Mark this with a width of 50mm. Draw a line at 30mm parallel to the others. Draw lots of little lines on the 20mm part that are horizontal to the other lines. This will allow you to curve the duplex while sticking. Look at the pictures to understand what I mean.

Begin to cut this out. It will look like a Thin, impractical brush. Using hot glue, you will now stick down the strip, making sure it is firm and tight. Now you have your mould.

Step 2: Step 2: Mixing the Concrete

Before you mix in the sand with the cement and water, it's best to mix the cement and the water. First, place the cement mix in the container. Add about 20ml of the water in small intervals, this will allow you to ensure you don't make any errors.

It's now time to add the sand. Never put in all of the water in one go. You will need to add about 100g then stir. Complete this step until the mix becomes like cookie dough. If you add too much or too little you will end up with a weak mix.

Step 3: Step 3: Pouring the Concrete

Place some of the concrete bit by bit until 1/4 of the mould is full. Tap gently just to release a few bubbles caught in the bottom. This also helps the concrete spread. Place more of the concrete mix into the mould until it is half full. Place the stick into the centre of the mould. The concrete needs vibrating before setting as it ensures the mould if definitely covered. Continue to add concrete until the mould is full.

Step 4: Step 4: Taking Off the Mould

After a day or two, it's ready to remove that mould. Taking off the mould is actually easy, just rip the card and then gently take off the residue from the concrete block. A good, cool method to check to see if the concrete has fully cured is to place a rubber mat over the concrete and wait a few moments before taking it off again. if there s a patch of moisture where the mat was placed, the concrete hasn't fully cured, so wait a few more hours.

Step 5: Finished!
