Kids who like science and crafts would have a great time making casting sand. You can make your own casting sand at home with a few simple ingredients. You will find a complete guide with detailed steps on how to prepare your casting sand for all types of projects.
In short, before you start to make your casting sand you must gather up all the ingredients that you will be using. All you will need to get started is here to combine some sand, cornstarch and water in a mixing bowl. Be sure to have a parent or adult assist you, as some of the steps can be tricky.
Gradually add water into the mixture, little by little. You want a little bit of moisture in that sand, but not too wet. If it’s too wet, just sprinkle in a bit more sand.
And use your hands to combine until you have a doughy mixture. If it seems too dry, add a bit more water. The sand should be somewhat dry; if it’s too moist, add more sand.
You have your casting sand now! You can form it into molds and leave it to dry overnight. When it’s dry, you can paint it or otherwise decorate it as you wish.
When selecting ingredients for your casting sand, opt for those that will help the sand maintain its form. Cornstarch works well because it can help the sand adhere to itself. Water also plays its role as it makes the sand easy to shape.
Making casting sand is an entertaining way to understand how things work in materials. The cornstarch in the mixture works like glue that bonds the sand together. Added to sand, water makes a paste that helps the sand particles stick together so they can be molded into shapes. When the casting sand dries, the water evaporates and you end up with a hard object that you can paint and decorate.
