Plastic bottles transformed! A collection of simple yet amazing craft ideas
“It’s made from a plastic bottle, and it can do that?!” There’s a wonderful world of crafts that’s sure to amaze everyone.
In fact, used plastic bottles are a treasure trove.
For example, you can make a curious drink dispenser where loosening the cap lets a beverage flow out through a straw, an ocean bottle that makes the most of the clear material, or a stained-glass lamp that glows dreamily at night—simple yet impressive projects galore! Try making some exciting crafts with plastic bottles you have at home!
Plastic bottles transformed! A collection of simple yet amazing craft ideas (1–10)
drink dispenser
It’s a clever setup where loosening the cap makes the drink pour out through a straw inserted into the plastic bottle.
The steps are simple: make a hole in the bottle, insert a straw, and then seal around the straw with a hot glue gun or adhesive so there are no gaps.
Eliminating gaps is crucial—this prevents leaks and also ensures that when the cap is tightened, the flow stops due to pressure.
Be mindful of the straw’s placement and angle as well, and fine-tune them so the drink pours smoothly.
PET-bottle air cannon
Let’s make a super cool-looking plastic bottle air cannon! Poke a hole in the bottom of a plastic bottle and attach a balloon over the hole to seal it.
Then add a handle and decorate it however you like, and you’re done.
When you pull and release the balloon, the air inside the bottle is pushed out through the mouth, launching a blast of air.
Try it on lightweight targets like paper or Styrofoam to see how powerful it is! This simple craft is not only fun, but also a great way to learn about air pressure and kinetic energy—perfect for a science project.
bracelet
If you’re starting to get into fashion, why not try making a PET-bottle bracelet? First, wrap masking tape around an empty plastic bottle and use it as a guide to cut out a ring.
Then use an iron to round off the cut edges, apply nail polish on the inside, and decorate the outside with rhinestone stickers—that’s it! Be sure to carefully check for any rough edges so you don’t injure yourself on the cut plastic when putting it on.
With a little creativity, the possibilities are endless—create a one-of-a-kind bracelet that’s uniquely yours!
Sensory water clock
This is a beautiful sensory bottle in which glitter-filled laundry glue flows slowly between two bottles.
To prevent any leakage, connect them securely by inserting a short-cut hose and wrapping vinyl tape tightly.
If you fix the liquid-filled bottles inside a case, it not only provides reassurance in case of leaks but also enhances light reflection—highly recommended.
Think about what kind of decorations to add to the liquid, and choose the decorations for the bottles and case to match.
Apple trinket box
The bottoms of plastic bottles have that bumpy shape so they can stand upright, right? Here’s a craft idea that uses that design: an apple-shaped trinket box.
Prepare two plastic bottles and cut out just the bottom part of each.
Stack the two cut bottoms together like a lid, and it already looks like an apple.
Using the remaining top parts of the bottles and some thick paper, make a leaf decoration and attach it to the top, and your transparent apple trinket box is complete! Using colored plastic bottles might make it look even more stylish.
Ocean Bottle
Perfect for a summer vacation science-and-craft project: how about making an ocean bottle that uses the separation of water and oil? Fill a plastic bottle about halfway with water colored blue and the other half with clear oil.
Then add seashells and other items to create a seaside feel.
Put the cap on, and…
that’s all it takes! Despite the simple steps, you’ll see a mysterious scene as if there’s an ocean inside the bottle.
Feel free to customize what you put in to make it your own!
10 Musical Instruments Made from Plastic Bottles
Musical instruments can produce all kinds of sounds and are fascinating, but many people may feel hesitant to buy a lot when they’re not sure how much they’ll actually use them.
Here, we’ll introduce many instruments you can make using plastic bottles.
For example, castanets made by attaching plastic bottle caps to cardboard, a whistle made by punching a hole in a cap and inserting a straw, and even instruments with different pitches just by letting the air out of a plastic bottle.
There are also plastic bottle drums and a “petphone,” made by connecting plastic bottles cut to various lengths.
Use these as references and give it a try!
Heron’s fountain
A Heron’s fountain is a hydraulic device invented by the inventor Heron of Alexandria.
Take two plastic bottles, lay them on their sides, make holes in them, stack them, and connect them using two straws of different lengths.
Then place another plastic bottle on top—cut it so the mouth remains—and, with the cap still on, make a hole and connect it the same way with a straw.
Be sure to seal the connected straws securely with a hot glue gun or similar so there are no gaps.
Add legs using caps or similar items to keep the bottles from rolling.
Pour water from the top, and once water has collected in the bottom bottle, flip the setup over.
When the water stops moving downward, flip it back.
Pour water again, and water should start overflowing from the top straw!
plastic bottle rocket
Soar high into the sky—why not try making a plastic bottle rocket? It’s one of the classic themes for summer vacation projects.
The mechanism uses compressed air pumped into the bottle to launch it using that pressure and energy.
While plastic bottle rocket kits are sold online, you can also make one with materials from a 100-yen shop, so if you have time, try building from scratch.
It might be fun to challenge yourself to see how far you can make it fly!
table lamp
Swoon over a glamorous finish as you take on making a table lamp! Start by cutting a plastic bottle into lots of square pieces.
Attach aurora film trimmed to fit each piece, then link them together using wire rings.
Hang the chain of pieces from a lamp frame you prepared in advance, and you’ll have a sparkling, beautiful piece of indirect lighting! Change the size and number of the bottle pieces or the color of the film to create a different look.
