Those “itchy bites” are actually reactions to mozzie spit.
While some things glow all the time, glow-in-the-dark paint must be ‘told to glow’ - just like a phone needs to be charged or it won’t work.
Mai Lam/The Conversation NY-BD-CC
You can see glow-in-the dark paint, but if you touch it, it is just as cold as the bedroom wall. So the glowing of the paint is different to the glowing of a light bulb.

Some spiders produce silk than can actually be stronger than steel and 50 times as light.
Hiccups might be a way to train breathing muscles and our hiccup reflex might actually come from our amphibian ancestors.

Birds can usually sense when they are not feeling well and like many other creatures, seem to seek out-of-the-way places to be alone.
Generally once a fortnight, someone at home will place the recycling bin out for a truck to drive past and empty your bin.

The short answer is that while lava is hot, it’s not hot enough to melt the rocks that make up the side of the volcano.
Only clouds that are tall with big water drops can make rain, but they also stop most of the light, which makes them look grey.
