ABC Gumball is the best as it work in about any act.. The one problem with alot of Wolf Magic products is they are alot of "Pick A Card Routines" So it hard to add more than one item to your act.. BUT because how professional they look they would be nice to have more than one in your act!
ABC Gumball kids and adults BOTH like it.. Currently I use: ( I have other items as mentiond in some older posts with me and Paddy fighting back and fourth

)
Warm up with some sponge balls....
ABC Gumball
Cellulator
Blow Your Stack
Wacky Wakoon (has a small pick a card routine and many other funny things!)
End with
Levitate the brithday child...
Then pull out the balloons!
All in my birthday short 30-45 minute show.. They look so professional like a stage show but play great in a living room as well..

I also have other effects but these are what I am using now.. (Axtel drawing board.
