"Food Pens"
Being able to draw and write a Bible verse or keywords onto food items is often an important aspect of making our lessons edible.
You can buy food pens at craft stores, but you can also make your own using food coloring and a pen cartridges.
The first video shows how to repurpose a washable marker to fill it with food coloring. The second video shows an inexpensive and reusable product called "Fantastix" (about $1 each at your local craft store) which you can use with food coloring.
Keep in mind that "what you're writing on" will make a difference in the appearance of the writing. More absorbing is better.

This next video demonstrates a "blank" pen called a FANTASTIX (originally made for inkers) that a food crafter repurposed with food coloring for easy writing. A pack of 6 is about $6. The demonstrator references their use with "inks" but she is going to fill them with food coloring instead.
