(CNN) - Here's a question you have probably never thought of: How high can a person build a Lego tower?
Thanks to British TV station BBC, we now know.
The BBC posed the question to some engineers. They tested how much force a small Lego brick could support. It found a single brick can withstand 950 lbs. of force, or 375,000 Legos.
That means a Lego tower could stretch almost 2.2 miles high. The BBC says that's higher than most mountains.
But, you won't see this anytime soon. Engineers say the tower would topple over and buckle well before reaching two-miles high.
