specifically, take a ceramics class and use the opportunity to make a piggy bank in the shape of a clock. it should be hollow but strong, with a slot that accepts coins. i will fill it with my mounds of change and then one day, smash it open.
i am stealing this idea from atypk’s ‘time is money’. their version costs $75, but by making it myself in ceramics class i am cleverly reducing the price to $300+
