We often use cardboard tubes for crafts (like with these adorable hanging bats) or for creative play (like in our car-themed sensory bin), but they can also be used to encourage children to explore the world around them. So grab some toilet paper tubes, paper towel tubes, or wrapping paper roll tubes and get busy creating all kinds of fun and engaging science activities!
Don’t want to repurpose old cardboard tubes? You can also buy recycled craft rolls in sets.
