Query: Works great but will not pass as "normal" b-day candles.

These come 10 to a pack and function as advertised. The only reason I give it a 4 instead of a 5 is that part of the prank is that the candle should appear as normal birthday candles. These on the other hand shoot off little sparks at the flame which is a dead giveaway that something is not normal. We played it off by announcing that they where "sparkler candles" hoping that would draw away suspicion. Not sure if it worked or not but a good time was had by all. My son did not give up until all the candles were out...some re-lit themselves a good 10-20 times.
