At Party City, the have these big plastic gumball things. I filled them up with candy (for DS bday) and they had this giant gumball machine i was able to rent (they delivered it cuz it's HUGE) and the kids took turns spinning the gumball machine handle and it spit out the huge gumball full of candy. It was pretty cool. I wish I had pics but BD was photographer that day and refuses to give em to me like a douche.
This is how the plastic gumball containers look. (They have em in all colors)
This is how the gumball machine looked (this was the closest I could find to it,. Idk how big this one is, but the one we had was 7ft tall)
If you have a party city near you, you should look into it. The gumballs were only like 2 or 3 for a dollar (I got 30 of them) and the gumball machine rental was $45 for an hour (an hour is plenty for the kids to have a turn at the machine). All together I paid a little over a hundred bucks including decorations and such. It was so worth it tho.
