Blue J Suprise!

A blue egg is produced out of thin air for a spectator. The egg is then placed inside the spectator's hand and closed.

After some niffy magic words the spectator opens her hand to find two eggs. The magician then produces three eggs inside the spectator's closed fist.

This is done once more, but this time a fourth egg is found. The four eggs are taken and the spectator is asked if she knows what's next. Five you say? Not quite.

Do you know what comes from blue eggs? Well, Blue Jays of course. The spectator opens her hand to find not only an explosion of the four eggs, but four blue "J's as well!
