my daughter wants to make magnetic putty. Would this be suitable to mix with a flexible putty and then use with a strong magnet?

I agree with Tony that the resulting magnetic putty may go rusty, depending on the oil and water content of the putty. Additionally, the grain size of the filings is somewhat variable. It would be an interesting experiment but I would be inclined to ask buyers of the premixed magnetic putty if it's flexible enough, and buy it on that basis.

How much is this in terms of tablespoons?

Not much more than one but enough to have fun with!

Can you mix it with water

Hello, Iron will corrode in water, therefore we wouldn't suggest this. Many Thanks Magnet Expert.

Could I mix this with blackboard paint to create a magnetic surface?

Do you know you can get magnetic plaster to plaster your wall with? We did it then painted it with chalk paint.

Good for magnetic slime

Great for making magnetic slime, although over time the oxidation of the iron made the slime become liquid again, rather than a non-nectonian fluid
