Science Buddies: "Ask an Expert"

Hello,
For my project's experiment iron fillings are used and so are Magnetic tape and a Digital scale with 0.1-g increments. On the page, it gives a link to these items on Amazon but my science fair is in 4 days, so the materials won't come in time. Do you know if there is anything else I could use instead of these items? Or if there is any specific place I could buy them from? That could really help.
By the way, my project's name is "Fighting the Flu: How Your Immune System Uses Its Memory", so you can find what I'm talking about.
Thanks

Hello! Here are a few suggestions that might help you out. You could try going to a local department store such as Target or Walmart - they may have some of these materials. You could also try a Michael's Arts and Crafts store.

Good luck with your science fair! Let us know if you have any more questions.

Alright, thanks
