Danny Dunn And The Weather Machine

This has a pretty bad example of how Danny never learns. He is told that he mustn't touch something but figures it's OK if he gets somebody else to touch it. I think even the 10 year olds this was aimed at would see that that is not OK.
Even after something bad happens because he (anf his friends) misused a device the Professor made,
they do it again.

The science in this one is more silly than science.
Not my favorite.
