Handmade Piggy Banks with Fun Mechanisms! A Collection of Summer Vacation Craft Ideas That Will Amaze Even Adults (31–40)
Piggy bank with a propeller made from a plastic bottle

Let’s try making a piggy bank with a three-tier propeller inside a plastic bottle.
Use a 2-liter plastic bottle as the main body, make the propellers from a milk carton, and use a bamboo skewer and a straw to create the propeller shaft.
First, make holes in the bottle to pass the shaft through.
Next, cut the bottle in the middle, insert the shaft through the holes, and attach the propellers.
Once the propellers are attached, glue the cut bottle back together, and finally add a coin retrieval slot to complete it.
Just saving money in a bottle can feel a bit dull, but with propellers like in this idea, you can save money in a fun way!
In conclusion
Piggy bank crafts you can make with simple materials are perfect for summer vacation projects.
There’s a wide range—from sophisticated designs with clever mechanisms that even adults will love, to easy versions that kids can make themselves.
With a favorite piggy bank, you get the joy of making, the fun of using, and the satisfaction of watching your money grow.
Your one-of-a-kind piggy bank will add a spark of excitement to everyday life.
