Then pry off the end of the marker using your scissors
Pull out the marker fiber inside. I sniped the plastic wrapping a few times to help the process along.
Insert maker tube into glue container
Wait a little while and then shake, shake, shake.
Voila purple glue.
***My daughter tried making some more this morning and they didn't turn out as vibrant, We realized for the purple (above) we used crayola non washable markers. I think it made a difference. For the washable marker kind we ended up adding two marker innards. We really sniped the marker tube up to let the fiber hang out (it's where all the juice is).
