KiwiCo Tinker Crate “Vacuum Chamber Review

 

Our Tinker Zine was all about air pressure this month with tons of educational information about how pressure works in relation to breathing and some great experiments such as making our own barometer or using our chamber for a pipette challenge. They also include some great further reading suggestions for us.

 

The directions for our project come on a separate sheet with illustrated steps broken into different sections. They always include helpful troubleshooting information as well.

Part A: Build the Pump

 

Our first step was to build the pump. They provided some rubber tubing, a syringe, a plastic beaker, some valves, and some tube connectors for us.

 

Testing Tube Set up

Then she tested it out to see if the air would come out of one side when she operated the syringe. It was a success!

Part B: Make the Chamber

 

Now it was time to make the chamber. They provided a base for us and a large plastic dome along with a rubber seal, a rubber stopper, a binder clip, and a brad fastener.

 

Testing Chamber

After placing the binder clip on one end of our tubing, we tested out our chamber by pumping the air out which sealed our chamber for us. Now it was time to experiment!

Using and Experimenting with the Chamber

Pipettes, balloons, bell, rubber bands

They provided two small balloons, two small pipettes, a bell, some rubber bands, and some foam squares (which we never used), for our experiments.

 

Of course, the balloon had to come first. I blew it up just a little, tied it and then placed it in the chamber. Liv pumped it and it got bigger, although it’s hard to see here.

 

Next came the marshmallows! We only had mini ones on hand but you can see here that the air came right back out of the single marshmallow after it blew up and when she did four marshmallows, some got bigger than others. She can’t wait to try bigger marshmallows next time!

Bell Experiment

We also tested the bell by connecting it to the brad fastener using the rubber band. This one had more to do with sound than anything visual which was cool to try out!

 

Then we used the little beaker to try out some dish soap and water!

 

She was super excited to test out anything she could so she ran around the house gathering different objects to try. Here she is trying out a marker cap. I loved how it sparked her curiosity!

Verdict: While it doesn’t happen every month, sometimes Tinker Crate sparks my children’s curiosity in the best way and it really transforms our experience into a lasting, educational lesson. This was one of those months and I loved seeing my daughter’s excitement and watching her try new things in her vacuum chamber. It really got her thinking about how it works and what types of items could be altered by the pressure. Assembling the chamber was very simple and everything was very well organized with a few fun experiments provided so that we can continue the learning with another lesson if we choose to. We had a lot of fun with this one!
