Looks like a good routine there, the production of candy, good to keep that at the end.
Here are a few suggestions:
Cut and Restored Rope I use Duane Laflins routine where the knots (3 of them) pop off the rope. Terry Herbert uses this with a patter about his shoelace breaking since kids can relate to that.
Magic Milk Pitcher
Kovari Pom Pom Sticks
Color Changing Shoelaces (about 10 bucks)
TT Blendo routine or Silk Blow tube (3 separate silks put into clear tube, when you blow them out they are tied together.)
Multi Color Rope trick-3 different color ropes, tie each into a circle and have kid blow on them or whatever, then toss into air and they change into one circle of rope.
Just a few ideas, I know some are expensive but others are like 10 bucks or so. Dan Harlan's Pack Small Play Big Birthday routine has some great ideas and most you can make at home with easily obtainable materials.
