Only 18 out of every MILLION Lego blocks don't pass the quality test.
At 0.00002%, that's quite an impressive success rate, especially for toy pieces that can be so small. They put Legos through numerous inspection spots. Machines perform drop, torque, tension, compression, bite and impact tests that are designed to ensure that the blocks are safe for kids.
Legos are placed in different bags and weighed to make sure the right pieces are going where they're supposed to go. Most Legos are packaged and shipped from the Czech Republic and Denmark. The factories produce 33,000 Legos per minute.
