That list is good but it could cost you a pretty penny! You do not have to go out and buy a bunch of props to have a successful kidshows. I own thousands of dollars worth of props now, but when I started kidshows, I made a lot of my own props!
Kid Biz is the best Ginn book you could buy in my opinion...and believe me...I have read many!
Zombie is a good STAGE effect...I would not reccomend it for use at a childrens birthday party...or any show where you will be level with the children or in their reach. Kids are curious...they will reach up and grab the cloth and try to jerk it away if you are not carefull...they will indeed sneak up on you and try this...it has happened to me a few times...
Now if you are doing a kidshow on stage...then by all means, Zombie is great...but like I said I would refrain from using it at a birthday show or any other similar show.
