Keep stirring until it starts to goop up. Don't worry, you'll know when this starts happening.
Just look at that little cloud of sliminess. The slime feels so cool.
Go ahead and add the iron filings and work them into the slime.
Massage the slime for a little while to make sure the iron filings are well-distributed.
Now, grab your magnet and start having fun!! You're going to need a really strong magnet if you want to see the fun effects.
Notes
Safety First: When working with borax and iron filings, it's important to take safety precautions. Wear gloves to protect your skin from any potential irritation, and avoid contact with your eyes or mouth. Additionally, keep the slime away from young children or pets who might ingest it accidentally.
Mixing Consistency: Ensure that the borax is properly dissolved in the warm water before adding it to the glue mixture. This helps to create a smooth and consistent slime texture. Stir the mixture thoroughly until the borax is completely dissolved to avoid clumps or uneven distribution.
Choosing the Right Magnet: To experience the magnetic properties of the slime to the fullest, use a strong magnet. Neodymium magnets, also known as rare-earth magnets, are particularly effective for this purpose. Experiment with different sizes and strengths of magnets to see varying effects and have more fun with your magnetic slime!
