Sci Fri: The Potions Master

Swelling Potion with Quill and Ink
 
Baking soda and vinegar is a regular sensory activity around these parts.
However, Unicorn Blood and Crushed Dragons Bones were a totally fresh take!
We even added Worms Guts (dish soap) that helped create the unique 'Swelling Potion!'

1 Part Crushed Dragons Bone + 5 Parts Dragon Blood
'Ex-swell-iarmus!'
