If your snake also stargazes it should be taken to a vet to check for IBD (Inclusion Body Disease), a not so rare but untreatable and rapidly fatal neurological disease.
If your snake is a Spider or a Woma, or at least is part Spider or Woma morph, then it is most likely just being weird like they often are. The term used for this behavior in them is called 'Wobble'.
Another time that can occur is during pregnancy, so if that's a possibility then it's probably that. It isn't exactly something to expect with gravid bp's, but it happens sometimes and isn't a bad thing.
I'm not sure what else it could be, but I've also heard that sometimes bp's just do that...for no reason. After concern and attention and blood tests and the like, nothing is found and it's just odd behavior. Apparently some like to randomly do that or lay partially on their side.

Dividing by a fraction is equivalent to multiplying by its reciprocal. A reciprocal fraction is effectively "turning it upside-down". So, to divide by a faction, you should do as stated; turn the fraction upside-down and multiply.
it's an h looking at itself in the mirror... or naah
it will close its wings and hang upside down on any thing that is his own color.

When a cockroach is turned upside down, it may struggle to right itself by using its legs to flip back over. Cockroaches have a strong instinct to stay upright, so they will typically try to correct their position when turned upside down.
Can you be more specific as to who does this?If you mean glasses already on the table when you are seated in restaurants, having them upside down keeps dust from falling into the glass and allows them to drain if they weren't QUITE dry when placed there.
