By: Jessica Hill on 5:00 AMIf you are looking for fun summer activities that still engage your child’s brain, get them to build a marshmallow catapult with you using the tutorial from It’s Always Autumn. They will get hands-on engineering experience AND have a blast. After the catapult is built you can create all kinds of fun games with the catapult that will keep your kids occupied for hours. I mean, who doesn’t like flying food? This would be a great event to keep the kids busy during your summer barbeque too.
