A visit from mr.z

Mr.Z payed a visit and taught us about gravity. We made miniature cars  too. These are the materials he gave us.....
 4 straws
Axles 
Tape 

This is how we made them
1.we cut off a bit of the straw and then stuck it onto the axle. We did this step twice
2.We got the wheels and we stuck them onto the axles.
3.We used the renaming straws and put them on the small piece of the straw using tape.

We all tested our different methods and had a race. Some went faster than others.
