Science for kids: making your own silicone mould

Science for kids can be fun because it brings the adult world to them in a new and inviting way. Moulds come in all shapes and sizes, but finding the perfect one can be challenging. Making moulds is relatively easy, and once created, they will guarantee hours of fun in the kitchen. Here is a step-by-step guide on how to create your own perfect silicone mould.

Use plastic gloves when kneading the silicone

Get a bowl and fill it with water at room temperature, stirring multipurpose liquid soap into it. Mix until the soap has dissolved into the water. As an alternative, liquid glycerine can be used. Buy some pure silicone, which can be obtained from DIY stores, ensuring it is not the quick-set type. Squeeze the silicone into the bowl so it covers the item.

Use plastic gloves to protect your hands and knead the silicon under the water. This process should take around five minutes. Knead it until it’s not sticky, ensuring that it remains under the water.

Carefully use your palms to shape the putty into a disc by rolling it into a ball and pressing down, making sure it is thicker than the item you plan to mould. If the silicone remains sticky, cover your hands and tabletop saver with a thin layer of the soap.

Let the silicone dry and form a hard shape

Press the item into the silicone, ensuring that the design side is facing down into the putty. Press the edges of the mould against your item, ensuring that there are no gaps.

Now it’s time to let the silicone dry and form a hard shape. It’s important to note that it will never turn completely solid. A degree of flexibility will always be there.

It’s not only children who can enjoy moulds. Companies rely on the products to ensure a smooth manufacturing process.

The Evening Standard details a choice of silicone mats, trays and moulds for cakes, and you can get the children involved to help create a sweet masterpiece.

The final step is to remove the item from the mould; it should emerge by itself. Place clay inside the mould, take it out and allow it to dry.
