Building Brains now offers a complete line of Birthday entertainment for ages 3 to 90. (We have noticed that most people NEVER outgrow the love of LEGOs. No matter what the age) Let us give your Birthday Party that something special that no one else has Building Brains while Building with Legos. We build dragsters, walkers, dogbots, and powerscars. (Please choose only one item to build per party, ages 8 and up) Party goers 6 to 7 years have an age appropriate list of motorized machines to choose from as well. Younger Birthday friends will build real machines that work using gears, levers and pulleys and watch them go. (ages 3 to 5 years) This Party is FUN-TASTIC!
