Knowing how to make putty is fun but knowing how to make magnetic putty that?s fantastic. You have everything that you need with some simple supplies around the house. And our secret ingredient, iron filings. Alright first, let?s do this putty.<br>
Dump an entire bottle of white glue into a mixing bowl. Fill the bottle with water and pour that into the bowl. Now before we mix it, let?s make our cross-linking water. This is a solution that actually takes these glue molecules and kind of hooks them together. So, in order to do that, Mule Team Borax. Put a table spoon of the borax into about eight ounces of water and stir it up. That?s good. Now, add the iron filings to the glue mixture. Now, you don?t have to be a chemist to understand that iron doesn?t dissolve in water so that?s why it?s gonna be important that you just get your hands in there and really mix it around.<br>
That?s good, so as you?re inside you can feel the iron filings sitting at the bottom. What we?re trying to do is to get them mixed up. When this starts to turn grey you know that you?ve done a pretty good job here. Now, we?re gonna take our cross-linking water and put that solution in there. Alright about that much. Again, not exact proportions. You?re just gonna feel it oh and immediately that?s looking good. But, not good enough so you really need to squeeze it around. And you really need to knead it with your hands. Mix it around and those iron filings now are going to be trapped inside. And so here is our putty. Like this. Look at this. We break it apart. That looks fantastic. But you can see the iron filings. They?re inside.<br>
Smooth out the putty to make it as thin as possible and then, grab your magnet.<br>
Look at this. Yes, there is goes. It just, it wants to jump right in. You know what? Look at this putty. This is one that I made yesterday. This putty here has rusted. And so overnight, you can see the rusting there. But here, let?s see if we can slowly start to pull it towards.. Look at this, that great. Look, this is great, yes. A little bit more. Look at that. Just a great way to be able to make a putty that?s magnetic because of the iron filings that are sitting inside.<br>
Well, what happens with our great big magnet? Well, I don?t know but take a look at this there it goes. I have a feeling it?s gonna be gone in just seconds as the putty almost comes alive works it way around and starts to eat that neodymium magnet.
