Build Your Own
|As with the other parts, there are many ways to make an axle which will support your bubble
wheel while allowing it to spin freely through the bubble solution. For our current purposes
we will focus on using a disposable ink pen, since they work great and are easy to describe.
But first, here are a couple of interesting tidbits. A coat hanger can also be used. Although
slightly less efficient, coat hangers can be bent to provide an axle that holds itself at the
proper height, etc. (at the same time)
Smooth is good. A smooth axle/shaft will have less resistance and spin better than one with
a rough surface. Dowel rods usually work fine, but often a smooth plastic or metal material
can work better.
Small is good too. A smaller shaft has a smaller area of surface contact. (which can greatly
affect it's performance due to resistance from friction) Interestingly, an 1/8" dowel is not as
smooth as a 1/2" plastic rod/outer pen casing/etc. HOWEVER, the size difference is adequate
for the wooden dowel to work better (between these two choices)
One of the best things that you can use for an axle is a dart from a blow gun (if adults are
making the bubble machines). They are very thin, straight, and quite strong.
However, a disposable ink pen works great - not to mention they are endlessly available and
don't even have to work. The inner part provides a great axle while the outer part makes a
perfectly sized holder/outer casing for the axle.
