Subject: heat pipe

Post:

I'm looking for some new heat activities for a qualitative lab. Anyone
have one of these:

https://www.teachersource.com/Physics/Thermodynamics/HeatPipeDemo.aspx

If you click on the Lesson Ideas link, it explains how it works. Was
wondering how well it works. Could a similar demo be made with just solid
and hollow copper (or steel) pipes with the same diameter and length?
Maybe to show how a solid vs hollow pipe heats/cools differently (as
hollow one has air inside).

I just want to have my kids experience some hands-on (non-mathematical)
things involving heat energy (e.g., fortune fish, bimetallic jumping disc,
remote and solar cell, liquid crystal sheet, lava lamp, etc.).

Other ideas?
