1 cup of flax seed
2 cups of water
Add both to a pot and bring to a boil
Once the mix comes to a boil lower heat and let simmer. You will notice it starts to become like goop. For me it took about 10 mins. Once done let it cool before giving to kids to play with.
Note~ this is a messy play item but has a great feeling!!
I herd of people adding food coloring to theirs and taking out the seeds, leaving just the goop...Personally I couldn't imagine how long that would really take, plus the seed give a nice texture. The brown color is also a color we don't play with much so I let it be.
Best part is this sensory play is all edible!
