Invention Ideas for Kids
Invention ideas for kids can change a boring afternoon into a whirlwind of fun. You don't have to be a rocket scientist to inspire your kids to reach for ideas beyond their traditional realm of thinking. Use these ideas to help your children learn to think outside the box, and experiment with common materials around the house to make fun and unique items.
A Balloon Powered Car
With a piece of cardboard, a balloon and a few other household items, your child can make a new toy. Set some goals for the car before creating it. For example, the car must go at least 10 feet when it is released. Let your child experiment with different shapes for the car and other additions, such as fins and weights to see how they improve or hurt the car's performance.
What You Need
- A deflated balloon
- Two wooden skewers
- Three drinking straws (one must be a bendy straw)
- A piece of cardboard
- Four plastic bottle caps
- A nail
- A hammer
- Masking tape
How to Make the Car
- Cut the cardboard in the desired shape. Make sure it is wide enough that the wooden skewers hang at least 1/4-inch off the edge on each side.
- Cut two straws to the width of the cardboard, and tape them on the bottom of the cardboard with masking tape. They will serve as the axles.
- Poke a hole in the center of each bottle cap with the hammer and nail.
- Place one wooden skewer through each straw.
- Attach the bottle caps to the ends of the wooden skewers to serve as wheels. If the wheels keep falling off, add a bit of glue to the hole.
- Tape the opening of the balloon to the short end of the bendy straw.
- Attach the straw to the center of the top of the car using masking tape. Make sure the balloon hangs off the end so that the short end of the straw sticks up.
How to Move the Car
- Blow up the balloon.
- Hold the open end of the straw closed.
- Set the car on the ground, and release the open end of the straw to let the air out.
A Stethoscope
All children must go to the doctor every now and then, but the experience can be frightening. Making a stethoscope at home and discussing how it works may help reduce a child's anxiety. It also opens the door to talk about how the heart functions and ways to keep it healthy.
What You Need
- Cardboard paper towel tube
- Funnel
- Balloon
- Duct tape (be creative and use colored, or printed duct tape)
How to Make the Stethoscope
- Insert the funnel into one end of the paper towel tube.
- Secure the funnel to the paper towel tube with duct tape.
- Stretch the balloon over the mouth of the funnel and secure with duct tape.
- If you want, you can wrap the entire paper towel tube with duct tape, or have your child carefully decorate with markers, stickers, or crayons, being careful not to crush the tube.
- To hear a heart beat, have your child place the funnel end of the stethoscope over someone's heart and his ear on the other end.
Ocean in a Bottle
This is a fun invention that stimulates creativity and introduces kids to ocean habitats. It also opens the door for discussing ways to protect those habitats. It's a great invention any time of year, but especially if you're planning a trip to the beach.
What You Need
- Empty plastic bottle, any size
- Funnel
- Tap water
- Blue food coloring
- Mineral oil or baby oil
- Glitter
- Small seashells
- Small plastic fish or other animals
Creating the Ocean
- Remove all labels and sticky adhesive from the plastic bottle.
- Using the funnel, fill the bottle about halfway with tap water.
- Using the funnel, add blue food coloring to the bottle. Be careful not to add too much, or the water will grow very dark. Replace the bottle cap, and shake to mix the contents of the bottle thoroughly.
- Using the funnel, add mineral oil until the bottle is full.
- Using the funnel, add glitter, seashells and plastic creatures to the bottle.
- Tightly replace bottle cap.
Water Xylophone
A water xylophone is the perfect invention for your musical child. Children can use their new musical instrument to compose water xylophone symphonies, or start a water xylophone band.
What You Need
- Five to eight empty glass bottles
- Food coloring
- Water
- A metal spoon
Making the Xylophone
- Fill each bottle with a different amount of water.
- Add a drop or two of food coloring to each bottle, giving each one a different color.
- Tap the metal spoon on each bottle to see what sound it makes. If any bottles are too similar in sound, add or remove water from one of the bottles to change the sound.
- Line up the bottles from the lowest sound to the highest sound.
- Tap the metal spoon on the bottles to play a song.
Experiment with using different types of glass bottles or mixing and matching glass bottles to change the sounds produced by the xylophone.
Egg Drop Container
Challenge your child to design a container for an egg that will allow the egg to drop from a set amount of feet without breaking. The exact design and materials for this invention will vary by the height the egg is dropped from and your child's problem solving skills.
Suggested Materials
- Small empty plastic tubs
- Bubble wrap
- Cotton balls
- Tape
- Cotton batting
- Packing peanuts
- Foam
- Cardboard
- Tape
Making and Testing the Container
How the container is created is entirely up to your child. You may want to add extra restrictions, such as not allowing the child to cover the container in layers of bubble wrap or limiting the size of the container. Use a ladder to drop the container from various heights to see how well the egg holds up.
Developing Invention Skills
Keep in mind that virtually any activity you do could inspire some type of invention by your kids. Help them learn how to look at the world with an eye for creativity, critical thinking, and problem solving. Once your kids begin inventing, they may be unstoppable!
