How To Make Plastic And Create Small Toys

Parents and children can work together to create a rubbery substance that kids can then mold by hand into small people, animals, and other objects. When the material dries, kids will have a collection of hard plastic toys that they can paint and play with – all with the thanks of the casein in milk.

Science Experiment For Parents And Kids

Because this part of the experiment requires cooking on a stove, parents should lead or assist in the beginning of this activity. You will need four ounces of milk and one teaspoon of white vinegar. Heat the milk alone in a pan until it curdles, or forms lumps. Carefully pour off the liquid. Put the curds into a small jar and add the teaspoon of vinegar. Leave the jar for at least an hour.

When you have a rubbery blob, pour off the liquid. Shape the material into whatever simple shape you’d like to create. You can paint the object when it dries, so don’t worry about adding too many details at this stage. Set the shape on the on a plate to dry for a few hours.

Science For Kids

The vinegar causes the milk to separate into a liquid and a solid mass made of fat, minerals, and the protein called casein. The casein is made up of molecules that can bend until they dry and harden. Early plastics were made from milk and plant materials. Nowadays, plastics are made from petroleum. Plastics years ago could decompose. Modern plastics can be recycled but they will not decompose.

Kids’ Crafts

After the shape is completely dried, kids can paint the objects with acrylic paints. After the paint dries, kids can glue on scraps of yarn, fabric, sequins, plastic gemstones, glitter, etc. Make certain that the paint or glue is dry before handing the items.

This casein plastic gives kids a lot of options for making small crafts. Kids could form egg-shapes and then adorn them in A Dozen Ways to Decorate Easter Eggs that they can hold onto for years. Children can also form small animal figurines to amuse themselves with during imaginary play. These small, decorated figures could also make gifts to friends and family members. Think of the person’s favorite animal and then craft it.

This science experiment turned craft project allows parents to show children how milk and vinegar interact to form a plastic. Kids can then allow their imaginations to take over as they form and then embellish the small plastic figures that they create.
