Harry Potter side-shows

[Hagrid]

My kids' Girl Guides group is planning a Harry Potter day. Can anyone 
come up with other ideas? 

We want to set up tables or booths with different activities. 

PS - no Blast Ended Skrewts please
**************************
Suggestions: 
"Beating the Bludger". 
We can do it shooting gallery style, but using a small club to hit a 
ball at targets. More points for hitting Chasers with quaffles, 
seekers, or keepers from the other team. 

"Hippogriff Rides"
Similar to barrel on ropes ride, landing on high jump cushions when 
you fall. 

"Rememberball"
Have ten items appear for 10 secs, then name them to stop the 
Rememberball from being red.

"Hermione Escaping the Basalisk"
HErmione tried running from the library using a mirror so she  
wouldn't be killed by the Basalisk. Competitors can either run  
through a maze where everything is reversed (like in a mirror). Try 
filling in a maze with a pencil while looking only in a mirror.

Quidditch match ???
we have basketball and football playing fields nearby. Any ideas on 
how to do it though?
