Introduction: Easy DIY Chalk

By

Today i'm going to show you how to make some sidewalk chalk from simple home ingredients you probably already have. I made two sticks of chalk but you can make as many as you want.

Step 1: Gathering Ingredients

All of these ingredients you probably have around the house.

1. Equal amounts of water and cornstarch, I used about 220 ml of cornstarch and 200 ml of water. (you may need some extra cornstarch)

2. Toilet roll tubes lined with baking paper.

3. Food colouring of your choice.

4. Something to put the tubes in so if it spills it won't go everywhere. (I used an ice cream bucket)

Step 2: Preparing the Toilet Rolls

To prepare the toilet rolls do this:

First, cut a strip of baking paper about 1¼ the height of the toilet roll. Then fold over about a ⅕ of the paper lengthwise. After That, Cut the strip to the circumference of the tube and roll that up smaller than the tube and put it inside the tube and fit the fold over the outside of the tube so that the inside of the tube is covered in paper. Rubber band a square of paper around the end where the fold is located, this will be the bottom of the tube

Step 3: Mixing Ingredients

Now that we have our ingredients, we need to mix them up so take the water and pour it in equally to each bowl then take the cornstarch and do the same for that, after that, put in a drop of food colouring to each bowl.

After you've put those into the bowl you can mix it all up with your hands or a spoon (hands work best). Eventually, your mixture will become hard when you mix, but liquid when you leave it, a good example of non-Newtonian fluid. Your mixture must be well mixed so there are no lumps or blobs of cornstarch.

Step 4: Pouring the Mixture

For this step I do not recommend using a spoon to scrape the excess out.

Take your mixture then pour each colour slowly into the tubes

Step 5: We Wait...

Now comes the step where we just need to be patient wait 24 hours (or more depending on whether its dry or not)

Step 6: Unwrapping the Chalk

To unwrap the chalk, snip the rubber bands with scissors and pull off the baking paper that it's holding on. Then, cut the cardboard tube down to the chalk then tear the rest of the cardboard off along with the baking paper.

Step 7: DONE!

Good Job, you've just made your cornstarch chalk and it works quite well for only being made with 3 ingredients.
