This might win the award for best STEM candle.

I bought the cake but totally forgot about candles! How can you have a birthday cake and not have candles?

Just before we cut the cake I recalled that I had one special candle left from a pack I bought maybe a year ago. I am still amazed at the level of engineering it took to make this thing work.

Thoughts I had:

How do they get the big flame to work without totally melting all the smaller candles?
Why does the wire stretch across the big flame?
Could you make a different candle to play a customized song?
How many version did they need to make before they found one that worked flawlessly?
How did they come up with this idea?
How much math was involved in making this?
Could you use different chemicals to produce a different colored flame?

UPDATE:

We took it apart to find the electronics inside. We found two batteries, a simple speaker and a tiny circuit board. The best part was the small strip of metal that was tightly wound which provided the power to rotate the flower.
