for pointing this out, you can buy unfilled markers
from Crayola! Saves some steps, that's for sure! I'm retiring my original set this year, so I'll give them a try. He mentions he's also trying them with Crayola's airbrush kit, I may end up trying that as well.
This is a very simple project. For you need only two things:
- A package of non-toxic washable markers
- Food coloring
For the markers, I went with Crayola brand, only because they are a name I'm familiar with, and I suspect if people had a problem with toxicity from their products it would be big news. It's not like a huge amount of anything from the marker itself is going to get into the food product, but it's better safe than sorry.
I got food coloring from the dollar store--you can pay 5-6 bucks at a regular store but I think this will do. As near as I could tell comparing it to the stuff I bought from Albertson's, it's exactly identical.
As to tools, you'll need:
- Several small glasses (like shot glasses)
- Lots of paper towels
- A surface that's either protected or you don't mind staining
- Watertight jar
- Plain white paper
- A heat gun or hair dryer
