via information aesthetics,
The three Germans behind Ballonmoleküle give lots of information on how to make molecule models out of long balloons, and explain why you would want to use balloons:
The balloons automatically adjust every angle in a way that an atom according to modern atom
models does, too. When three balloons meet at one knot (at the atomic nucleus so to speak), they
act just like a sp2-hybrid atom which means they form a planary system.
When four balloons meet, they form a tetrahedral. You only have to keep in mind to build some free
electron pairs as well. If you do this for example for water, there will be a smaller angle than for
a tetrahedral, since there are six balloons that meet in one knot (two compounds for the hydrogen
atom and two each for one free electron pair).
They even get a shout-out from Francis Crick: "It's really remarkable how you have been able to show the key elements of the double helix
with balloons."
Next time you're at a fair, ask the clown with the balloons to make you a Cuban cluster [Fe4(n5-C
5H5)4
(µ3-CO)4]:
