Meet Tristin and Tyler, 8-year-old twins and the hosts of the web video series Tristin & Tyler’s Tales from the City. They’re out to save the Earth one project at a time, and have a fun, new challenge for KIWI Kids: Repurpose trash to save cash for charity! Make a piggy bank out of a pasta box, then use it to save money. How much can you save to donate to charity by the end of the summer? Watch Tristin and Tyler’s video tutorial to see how they made their recycled piggy bank, plus get ideas on kid-friendly charities.
