Hello dear @lemouth thank you for your important visit and for your words are valuable to me.

As a side note, right now it's school vacations in France, and my wife and I were looking for simple science experiments to do with the kids. I'm definitely going to add these two to the list. They are great and simple to put into practice!

That's right my friend they really are very easy to put into practice and get a proper understanding of atmospheric pressure, and have a great weekend.
