    This has always been strange to me. I’m assuming you live in North America. The honey bee is not native here. They are therefore an invasive species, but one that even environmentalists are fine with.

    I don’t know enough about the whole thing to have an opinion different than the norm, so I support you providing a habitat for honey bees. It just confuses me.

    All honey bees are nectarivorous pollinators native to mainland Afro-Eurasia,[13][14] but human migrations and colonizations to the New World since the Age of Discovery have been responsible for the introduction of multiple subspecies of the western honey bee into South America (early 16th century), North America (early 17th century) and Australia (early 19th century), resulting in the current cosmopolitan distribution of honey bees in all continents except Antarctica.[13]

    I guess it really depends on the mass difference between the other liquid and the wax. If they’re almost the same, there shouldn’t be much net force. If they’re drastically different you might see some net external force produced. Since the blobs move slowly in the liquid, we have to expect the densities are at least comparable. I’d think the net movement of mass is too.

    That is super interesting about the hourglass. I never considered that, but it makes sense. The sand is transitioning from a higher energy state to a lower one within a gravitational field. Each grain gains momentum during the fall, then exerts that force on the structure when it hits the bottom.

    The lava lamps don’t start in a stored energy state. They add thermal energy that causes the convection, but the entire time there’s a conservation of momentum within the lamps.

    It’s super cool idea, but I’m pretty sure the chandelier would be stable, not wobbly.
