My sister and I were baking apple pie last week, and I took the seeds out of the cores of the apples we used and put them in a glass with wet paper towels to grow them. One had already sprouted inside the apple, and then another one has sprouted, barely big enough to see.
Keeping track of its growing progress here.
It will be significant if it grows to a seedling because it will be the first thing I've grown successfully on my own. XD
