The next free Kids Workshop at Home Depot will be held on Saturday, August 5, where children will be able to build a free Penske truck. These workshops run from 9am-12pm and are aimed at kids aged 5-12, though the age range is simply a guide instead of a strict rule. I can also confirm grown adults aged over 30 sometimes have trouble helping their little brother because I'm terrible with tools.
There are only a limited number of spaces available, so you need to register online ahead of time! However, back when I used to take my little brother, they didn't force you to arrive at 9am sharp. We would often show up around 10am and have plenty of time to get the project finished before noon!
In addition to the free truck, children receive a free certificate of achievement, a Workshop Apron, and a commemorative pin while supplies last.
