In this Instructable you will find instructions for a simple fool proof soccer goal that a five year old could make for around $40.
Step 1: Parts and Tools
-4x 10 Foot Lengths of 1-1/4 Inch PVC Pipe
-6x 90 Degree CONDUIT Elbows
-6x 1-1/4 PVC Couplings
Step 2: Cutting
Cut 2 of the 4 pipes in halve (5 feet). Leaving You with 4 pieces.
Step 3: Assembly
Make the pieces in the pictures.
-2x 5' pipes with two elbows each
-2x 5' pipes with one elbow each
Add a 10' pipe in between the pipes with two elbows each
Add a 10' pipe in between the pipes with one elbow each
Put it all together
Step 4: Net
This is the link to the net I am going to order I will update the pictures then.
Do NOT get this net I sadly learned that the aditional foot and a half added by the elbows throws off dimensions. I am sure there is still a net that will fit out there somewhere.
