Fund Raising Idea #76....Day of Idea....this is hilarious - I found it online.  I will publish the directions I found below.  But.....paint this purple and make a sign that says FLUSH AWAY CANCER.....You could have it at your tent site - put it back behind a table and people stand at the table and throw the toilet paper rolls.  The idea for tootsie rolls as the consolation prize was pretty cute :)  Good luck.....this could be really fun...

Carnival Game Idea – Toilet Paper Toss

Carnival Booth Supplies – Toilet Paper Toss:
Toilet Paper Toss Game (see directions below)
3 or more rolls of Toilet Paper either individually wrapped or taped on the outside with duct tape to prevent unraveling.  
Carnival Prizes – top, medium and consolation. Note: we love to use small tootsie rolls as the consolation prize for this booth – they cost pennies and the kind-of go with the toilet theme! :) 
 

How to Play:
Before the carnival, set up the Toilet Paper game and make a few different lines for different age groups of children. (Younger children will be closer to the game to make winning a little easier). Players get three chances to toss the TP roll into the “toilet”. If they get 0 or 1 they get a consolation prize. If they get 2 in, they get the middle prize. If they get all three in, they receive the top prize. 

Make the Toilet Paper Toss Game:
Supplies:
New, donated toilet seat. Ask a local building supply if they have a damaged (new) seat they would donate to you for your game.
Plywood, possibly donated, to construct the box with a back to support the toilet seat
Paint to finish the look (see photo above)
Obviously, you will need a volunteer who is good at constructing things with wood and possibly someone else who can paint your game booth and make it look nice.
