Feed the Elephant: (Charlie painted this on a washing machine box and used a dryer vent for the trunk.) The kids would place peanuts in the trunk to "feed the elephant" and raise the trunk until the peanuts dropped inside.
Circus party - hotdog bar cook hot dogs for a crowd, no water needed. This worked great for my daughter's preschool carnival day! I had mine set to 'keep warm' for a few hours before. The hot dogs steam up perfectly.
Prize for ping pong ball toss. This gives me a couple ideas: Candy tackle box, fish stuffed animal, real fish w/ mini bowl (ketchup cups w/ fish food & lids), any fish shaped food treat, or even beach toys!
Bath paint cup shampoo/ or hand soap/ or body wash (use whatever soapy thing you have lying around, great use for shampoo you didn’t like, or the end of the body wash) cup corn starch TBS water drops food coloring. My kid LOVED this!
