Poundland Harry Potter style floating candles

These turned out to be pretty good. Initially when I saw the box I thought they were just floating tealights, but it turns out they are slender electronic flickering candles that come with a hook and very fine clear thread to suspend them in the air.

I'll guess they may be themed on the floating candles in the banquet hall of Hogwarts.

The circuitry is actually pretty impressive, since it uses a single AAA cell at a very low 11mA with a 3-pin boost chip that ensures constant intensity of the flickering LED right down to about 0.6V.

Note that it's extremely easy to tangle the very thin threads, so I recommend only removing one candle from the pack at a time to hang them. When taking them down, remove the battery and roll the thread back up round the body before placing in the storage tray.
They can be untangled and the threads adjusted as shown in the video.
