We were walking through Walmart when we saw some Angry Bird stuffed animal toys for sale. My wife and I looked at each other and said "we need to build a life sized Angry Birds Game". So, we bought some stuffed Angry Birds, some wood, various hardware, and rubber tubing and built a life sized Angry Bird Game.

Step 1: Materials & Tools

Materials
2 foot by 5 foot 1/2 inch thick plywood
2 - 8 foot 2 x 4s
1 - 8 foot 1 x 4
2 - hurricane straps
1 scrap piece of 1 x 6 for the pigs
1 scrap piece of 1 x 2 for the small bases of the pig
paint
nuts, bolts, nails
rubber tubing from Exercise Band
3 stuffed (plush) Angry Birds (you might be able to use homemade bean bags with angry birds on them).

Tools
Circular saw
Scroll saw (manual or electric)
Drill
Knife to cut tubing
Hammer

Step 2: Build the Base

We built a 5 foot by 2 foot base out of 1 x 4s and 1/2 inch thick plywood. We wanted a platform big enough for people to stand on while pulling the exercise tubing back so the weight of the person on the base would help stabilize the sling shot structure. We added an additional 1x4 joist at one end and cut a 2 x 4 inch groove in the plywood base so we could slide the slingshot into the hole and attach the base of the slingshot with 2 bolts and 2 wing nuts. We designed this to be somewhat portable for ease of storage and transportation.

Step 3: Build the Slingshot

Cut one 2 x 4 about 32 inches. This is the long base pole of the slingshot. Cut two 1 foot pieces of 2 x 4. These will be the two arms of the slingshot. Cut two 22 inch pieces of 1 x 4. Attach the two 1x4 pieces to either side of the 32 inch long 2 x 4 at a 90 degree angle. I used 8 D nails. Slide a 1 foot section of 2 x 4 on each side of the arm (between the 1 x 4s). Attach using 8 D nails. Drill a 3/8 inch hole in the center of each arm about 3 inches from the top of each arm. This is where rubber tubing will be attached.

Step 4: Putting It Together

Cut an 18 inch long piece of 2 x 4 at 45 degree angles on either side. This is a brace for the slingshot. Attach a hurricane anchor metal bracket to the base of the angry bird platform and also one on the slingshot. Hold your brace up there to determine where to attach the hurricane roof brackets. Put the slingshot through the slot in the base. Drill two 1/4 inch holes through the base and the slingshot. Insert two 1/4" bolts and tighten with lock washer and wing nuts. I do this to make the whole base portable for easier storage and transportation. Drill a hole on either side of the 2 x 4 brace and attach one end to the bracket on the base and one end to the bracket on the slingshot. Fasten with 1/4 inch bolt and lock washers and wing nuts. Cut two 2 feet lengths of exercise tubing. I bought this at Dick's Sporting Goods. I tried some old surgical tubing that I had around the house, but it broke. Get a piece of leather about one foot long and 5 inches wide. Put a grommet at either end. Attach the tubing to the slingshot and leather pouch.

Step 5: Cut Out and Paint Pigs

Using a scroll saw, cut the four angry pigs out of 1 x 6 pine. Just explode and trace the attached picture for a pattern. Cut four 2 inch long pieces of 1 x 2 for the base of the pigs so they are not so easy to knock down. Glue and attach the 1 x 2 bases to the bottom of the pigs. Paint the features on the pigs. Get some empty boxes for the pigs to hide behind. I used whatever I had around. The cardboard children's blocks/bricks would be neat to use.

Step 6: Play Life Sized Angry Birds

Set up the blocks and pigs. Find some kids that want to have fun and start playing angry birds. It's a little bit healthier than the phone angry birds in that it gets kids some exercise pulling back the exercise band on the slingshot and running up to set up the pigs and retrieve the stuffed angry birds.
