For my daughter's 10th birthday we had a fear factor party.  We made invitations on the computer - stating "If fear is not a factor for you, then you are invited..."    Because approximately 30 children showed up (ranging in age from 6-11) we decided to divide the children into 3 teams for the first 2 events.  Event #1 Egg Pass  The 3 teams were told to line up facing front. In front of them was a table with a box of eggs on it. The first person in each line had to take an egg and crack it in the second person's hand. The second person had to pass it to the third person and so forth.  Behind the last person in line was a bowl.  The goal was to have the most egg yokes in the bowl at the end of 30 seconds.  The team with the least is eliminated and the two remaining teams moved on to event #2.  Event #2  Dirt Dig  The two remaining teams were again told to line up facing front. In front of them was a table with two small pools (purchased at the Dollar Tree).  Each pool was filled with dirt, worms & pieces of clothesline. The first person in each line had to dig through the dirt & worms in the pool to find a piece of string.  Once the string was found it had to be placed on the table and the second person in line went next, then the third and so forth. The first team to have everyone in line find a piece of string wins & moves on to event #3.  Event #3  The picnic  At this point there was only one team left (approx 10 kids)so we allowed them to compete individually. On a table was a cooler filled with various condiments, index cards with the name of a condiment written on it & mini Dixie cups. Each contestant had to pick three cards - the cup was filled with a little of each condiment that  was written on the cards(sometimes child picked three of the same card.  The child had to eat the contents in the cup within 10 sec. to move on to the next event.   Event #4 The Worm Tray  On a table was a silver platter of worms & dice.  Each child was asked to roll the dice. The total number showing on the dice was the number of seconds that person had to put the cheek in the plate of worms.  Anyone not able to do it do not move on to the next event (surprisingly everyone moved on).  Event #5 Dart Board On a dartboard were numbers the numbers 0, 1, 2, 3 & 4. The children had to throw a dart (the board rotated) and whatever number the dart landed on was the number of Jell-O cubes they had to eat.  One catch - the Jell-O cubes (made using ice trays) had a bug in the middle (the bug was actually a raisin but the children did not know that). Those that were able to complete the challenge moved onto the final event. Event #6 Ring toss  For the last event, a wading pool had been filled with water and ice. The first child (There was only 4 children remaining at this point.  And one was only 7 yr. old) was given goggles and told to get on their hands and knees. Thrown into the water was 12 small teething rings. The challenge was to pick up the rings using your mouth. The child who picked up the most rings was the grand prize winner of a $10 bill. Everyone else making it to the last event was given $1.  This party is very messy.  However, it is inexpensive & most importantly the children love it. Even the children that were eliminated early in the game had a good time laughing at others and cheering for others.  We video taped the whole party and the children enjoy viewing the tape again and again.
