Head into the kitchen with a few basic ingredients and show kids how to make a homemade Silly Putty solution out of white glue and Borax. Not only is this an enjoyable activity, but children can also learn a lesson about polymer materials and how molecules work in polymers. When you are done making the Silly Putty and learning all about the chemical processes, kids can then have fun moulding and shaping their concoctions.
What You Will Need:
- Measuring spoon and cup
- 1 qt. jar with lid
- Label or marker
- 1 zipper plastic bag (quart size)
- Non-Toxic White Glue
- Food colouring (optional)
1. Pour 240ml of warm water into a medium-size jar, add 1 tbsp. of borax and gently shake it up until powder dissolves. Label the jar for storage identity and future use. Set aside until ready for use.
2. Put 1 tsp. of water into a quart size, zipper bag along with 1 tbsp. of glue. Add a drop of food colouring to the mix to make your homemade Silly Putty colourful
3. Add 1 tbsp. of borax mixture to the glue and water. Zip the bag shut and squeeze the ingredients between your fingers until it forms a putty-like substance.
4. Remove from the bag after two minutes, squeeze it with your hands to desired consistency and enjoy the new Silly Putty.
5. Place the homemade silly putty in a clean zipper bag and store in the refrigerator to keep it fresh. Make a new batch from the stored Borax and water mixture as often as you like.
Tips & Warnings
- Substitute the jar with an empty plastic soda bottle with cap, if necessary.
- Purchase good quality zipper bags to prevent leakage during the mixing and squeezing process.
- Do not leave children unsupervised while making the homemade putty, and do not allow them to taste or eat the substance.
- Do not leave the Silly Putty on clothing, carpeting, upholstery or wood as it may stain.
- Do not pour any of the putty ingredients down the sink drain.
- Store the labelled borax and water mixture in a safe place away from children.
