My son's pocket knife was stuck and broken. So one evening he and his brother (they are 4 and 7 years old) picked it to pieces, marveling at its individual parts, including the snap ring from its broken chain. They then reassembled it, turning it into a pendant for the courageous and gave it to me as a present. I wear it on my finest gold necklace now.
Conclusion: There is something special waiting in every broken little thing.
And: Children are natural born talents at upcycling.
