DIY Balloon Powered Cars You Can Make For Science Lesson

by

This roundup is all about Balloon cars and making them. Not only do you get the thrill of engineering and developing the toy you get to play with it afterwards. This activity has so many opportunities for educational homeschool learning. STEAM is represented in all of these DIY tutorials. I have included different styles of Balloon race cars to give parents the flexibility of using the supplies they have on hand at home.

Science Sparks has a version of the popular Lego car that is powered by a Balloon here.   Frugal fun 4 Boys also has a lego version, this car is a simpler design so more suited to younger engineers.

This one by  Tots to Teens uses recycled materials making it the easiest one to source the supplies for followed by this one which uses a Juice Box and bottletops.   For a recycled water bottle tanker you will need this tutorial by pbskids.org

I love the design of this Race car, actually, it’s more like a drag car but you will need old CD’s does anyone still have those in the house?  This tutorial is a video and uses card board and milk lids a very simple design but has the same concept.Vroom Vroom with this simple box style car.

Don’t have the items? You can purchase ready to go Balloon Car kits too.

The Science behind it all –

A balloon-powered car is pushed forward by air escaping from a balloon. As the balloon fills with air, it adds more potential or stored energy. As the air flows from the balloon, the energy changes to kinetic energy or the energy of motion. Vehicles are powered by the escaping air from a balloon teach children Newton’s third law of motion. Minimize the drag and reduce weight to make the car go faster. Try running your car on different surfaces for speed too.

This video shows you the science, make your car and watch it here. 

Here are some video tutorials on making your own Balloon Car Too

Add a Little Lace to Your Knitting Patterns

If you’re new to lace knitting or just aren’t sure how to incorporate the technique into garments, check out these tops and sweaters that use lace as a decorative element.

The easiest lace out there is eyelets, and you can practice them plenty with this eyelet covered sweater from Knitcro Addict. It uses light/DK weight yarn and is worked in four pieces knit flat. It’s intended to be a little cropped and a little oversized, and includes sizes XS to XXL in the pattern.

If you’re in parts of the world where it’s getting colder as you read this, the Nora sweater from Bummbul might be a good choice. This is actually a great one for learning lace because it’s worked in super bulky yarn, which makes it easier to see what you’re doing and makes the lace super graphic. This one just comes in one size, with a 42 inch (106) cm bust, but that could fit a variety of people depending on how much ease you like.

Minimi Knit Design has a cute allover lace cardigan worked in one piece from the bottom up. It’s worked in lace weight mohair held double, which maybe isn’t the best for those new to lace (because it can be hard to rip out) but it sure is pretty. Sizes range to fit from 30 to 66 inches/76 to 168 cm bust measurements.

If you’d rather not have lace all over your sweater, you can knit the Lumi sweater from Originally Lovely, which has a chevron lace pattern on the yoke and is otherwise worked in reverse stockinette stitch. (It’s worked inside out so you don’t have to purl every stitch.) The pattern has 9 sizes from XS to 5XL and uses worsted weight yarn.

Or try the super romantic sookie blouse from Trust the mojo (available on Ravelry). This sweet top is started working flat from the bottom up and has a V-neck and I-cord edgings. The sleeves are worked separately in the round, and the pieces are all joined together to work in one piece to finish off the top. It comes in eight sizes and is available in English and French.

You can also pair lacy sleeves with an otherwise plain top, like on the Starflower Wrap from Annelise Driscoll Gingrow. This intermediate pattern makes a wrap sweater with generous lacy sleeves and a double wrap belt. The pattern has nine sizes, from XS to 5XL, and is available for free from Hobbi.
