This is a re-boot of how to make magnetic silly putty, with some interesting changes!
This is a simple way to change the viscosity of store bought Silly Putty and add magnetic properties. Using scrap iron filings Silly Putty and a cheap source of Dimethecone.
Step 1: Three Simple Ingredients
1- Silly Putty
2- Dimethecone; easily sourced from RC hobby stores as "Shock Oil"
3- Collect/Make iron powder
The iron I got from my metal lathe. When you machine cast iron, it makes small chips.
Step 2: Grind and Mix
Use a pestle and mortar to grind the iron filings into fine powder.
Mix the Silly Putty with the Shock Oil and Iron Powder.
Add small amounts of shock oil to the silly putty, until you get the consistency you want.
Step 3: Play!
The silly putty will slowly creep toward any strong magnet, even straight up in the air! You can get the silly putty to dance by moving the magnet around.
I used glow in the dark silly putty, so here I'm blasting it with a UV laser to get a cool glow.
Silly Putty and Dimethecone is considered safe and inert. If you've ever eaten anything fried at a fast food restaurant, you've eaten it! It is used as an anti-foaming agent for the fryers.
