Summer has a way of turning your recycling bin into a pile of potential. Between the cardboard tubes, empty bottles and flattened cereal boxes, there’s a lot just sitting there waiting to become something. These upcycled craft projects give kids a hands-on way to make something fun out of what would otherwise head straight to the curb.
1. Cardboard Tube Rockets
Cardboard tubes left over from paper towels or wrapping paper make surprisingly good rockets. Cut fins from a spare piece of cardboard, tape them to the bottom of the tube and add a cone of paper for the nose. Children can paint them however they like. Silver and red are popular choices, but there are no rules.
This kind of open-ended building is more valuable than it looks. Unstructured creative play supports problem-solving skills and builds independence in young kids. It’s a good excuse to let them figure things out on their own for a bit.
This is best for ages 4 and up. Younger ones will need help making the cone.
2. Egg Carton Caterpillars
Cut an egg carton in half lengthwise so you have a row of six connected cups. That’s your caterpillar body. Add pipe cleaner antennae, googly eyes and as much paint as your children can handle.
What’s nice about this one is that it’s almost entirely child-led. There’s no wrong way to decorate a caterpillar, which makes it a low-pressure activity for kids who get frustrated easily. Art like this gives them a way to process and share their feelings without needing the right words, which children’s art therapists describe as expressing big feelings through creativity.
This is best for ages 3 and up. It’s a very toddler-friendly activity.
3. Water Bottle Fish
Rinse out a plastic water bottle and let it dry completely. Kids can stuff the inside with colorful tissue paper so it glows when held up to the light, then add fins cut from craft foam or cardboard and draw on a face with a permanent marker. The result looks genuinely impressive hanging in a window.
This is a good one to pair with a quick conversation about recycling. Studies from the EPA show that plastic makes up a significant share of municipal solid waste, and children who understand where materials go tend to be more thoughtful about it. You don’t have to make it a whole lesson — just casually mentioning it tends to stick.
This is best for ages 5 and up. It’s great for a sunny afternoon near a window so you can enjoy all the colors.
4. Milk Carton Bird Feeders
Clean out a half-pint or pint milk carton and cut a large opening on one side. Poke a stick through the bottom as a perch, run a piece of twine through the top for hanging and fill it with birdseed.
Watching birds actually show up is surprisingly exciting. Time outside has measurable benefits, even if you’re just sitting and waiting for a visitor. Outdoor time supports children’s physical and mental well-being in meaningful ways, and a bird feeder gives them a reason to keep coming back outside.
This is best for all ages. Even very young kids can help pour the birdseed and will love watching all the feathery friends flocking in.
5. Cereal Box Puzzles
Cut out the front panel of a cereal box and draw a simple picture on the blank side or use the printed side as is. Then, cut it into pieces. The number of pieces depends on the child's age — six or eight for younger ones, more irregular shapes for older ones. Store the pieces in a small zip bag so they don’t get lost before the next time you build the puzzle.
It sounds too simple to be worth it, but kids genuinely love puzzles they made themselves. Research indicates that this play builds early spatial reasoning skills in young children.
This is best for ages 3 and up. The difficulty of the puzzle is fairly easy to adjust.
6. Tin Can Planters
Rinse out a tin can and make sure there are no sharp edges on the rim. Sand it down if necessary. Kids can paint the outside however they like, let it dry, and help fill it with a little soil and seeds. Sunflower seeds and herbs like basil or mint are good choices because they sprout quickly enough to hold their attention.
There’s something satisfying about watching something grow from something you made yourself. It’s a small lesson in patience that tends to land better than most.
This is best for ages 4 and up. Older ones can take full ownership of the planting.
7. Newspaper Boats
Fold a sheet of newspaper into a simple origami boat. If you don’t know how, thankfully, there are plenty of step-by-step guides online. The goal is to see how many pennies it holds before it sinks.
The test can take place in the bathtub or a bucket of water. Older children can try to engineer a better design. This project is good for a quiet afternoon when everything else has been tried. It encourages the outdoor and imaginative play kids need, and a soggy newspaper boat is a satisfying ending.
This is best for ages 6 and up for the folding. Younger ones can supervise the penny test.
A Recycling Bin of Possibilities
Summer is long, and kids need things to do with their hands. However, none of these projects requires a special trip to the store. The next time you’re about to toss an egg carton or rinse out a bottle, it might be worth asking if your child wants to make something out of it first. You might be surprised by what they come up with.
