Teacher Created Resources STEM Starters: Hydraulics

These are a great Balloon car for the Girl Scout Balloon Car Badge. The girls had a lot of fun making these and racing them. This was the second time we used them for this badge! You do need cardboard to put them together - a great use for your cookie case boxes!

Ideal for parents to train their kids. Minimal use of water to demonstrate hydraulics makes it an all time stand-alone toy kit also. Just connected two syringes at two ends with water inside, and saw the fun of my three year old playing it around and even carried to her pre-school..

These were fun to use on an dyi hydraulic garage door built for my nephew. The connection between the syringes and pumps wasn't the best but still fine for what I was trying to accomplish

Easy enough for my 2nd grade kid. Worked well to add. We had to build a egg drop to go off of a fire fighter ladder and it worked so well!

Great purchase.

This kit was so low quality as to be useless and largely frustrating for kids. I do not recommend.

Great for finishing the balloon cars for the Girl Scouts badge. All you need is a frame or box for the body of the car. You can make 2 style if I remember right. The girls had fun creating their balloon cars and they were easy to use.

I bought these for my science class as we were doing a unit on gravity, force, motion etc… well first of all, - there is no where for the straws or sticks to connect. They say to tape them together on the little piece of paper that comes with them (no instructions- yes I know it’s pretty self explanatory but not to students). - second, the balloon mount for the car does not stay on with tape very well at all. Now don’t get me wrong, I absolutely love the idea of everything being together in one packet for the students, but if there was some sort of pre drilled, reenforced holes for the sticks and straws, and everything to connect, there was an actual clip that held the balloon attachment on, and the wheels were able to actually roll— this set would be awesome!!!! I just feel it was made super cheap and I get that. I truly understand. I was pretty disappointed in these, unfortunately. Great idea!! Poor design.
