Hot Hot Hot

Today's theme is: Hot

Well as I got up this morning I thought, amongst other things, what is hot?

Well the sun is hot, but there's no sign of it here (surprise surprise) so the weather isn't even hot
My morning cup of tea is hot but you can't really capture the hotness of tea in a photo
You can have hot water taps (but none of the taps in my house say hot or cold)
My hot water bottle filled with hot water is hot, and it is a see-through one too...but that doesn't work in a photo
A boiling kettle is hot but I couldn't capture the steam

So then I thought well fire is hot. But it's the wrong time of year for bonfire night to get a bonfire or fireworks, I don't have a nice coal fire (or gas or electric for that matter) in my house so next stop is candles to get some sort of flame thing going on.
There was a time I had quite a few candles but now I only have a box of tea lights that get used once a year for pumpkin lanterns on Halloween.

So here is the closest I can get to HOT via photo.

Can you feel the heat?
