James May built a full-sized LEGO house for his TV show James May's Toy Stories on the BBC back in 2009 using around 3,500,000 bricks. Whether you'd actually want to do this yourself... During the episode they spent some time with engineering students working out the most load bearing configurations of bricks especially for the upper floor, as well as ...


The main restaurant in the LEGOLAND park in Windsor has quite a lot of LEGO creations in fishtanks. In the same park, the Sealife attraction 'Atlantis Submarine Voyage' has 50 species of sharks, rays and tropical fish that happily coexist with the LEGO models. Keep in mind that LEGO is safe from children saliva, which I'm willing to bet is more aggressive ...


No, you should not be concerned about lead. LEGO has always used lead-free colors in their elements, even back in the beginning. However, not all LEGO-compatible bricks are lead free. For example, Mega Bloks, which are made in China, suffered from the poor quality control that led to massive recalls over lead-tainted products a few years ago. David ...


What could be considered a safe limit that motors can endure for an extended period of time? Their rated voltage. Motors are designed to operate at their rated voltage indefinitely, or until they wear out, whichever comes first. Exceeding this voltage means you shorten the life of the motor. Your big enemy is heat. At some point, the amount of ...


The most obvious risk is swallowing parts, even though at that age it's probably less likely to happen. Magnets are the most dangerous, but LEGO has done a good job of hiding them recently. Projectiles are also a risk, whether they are intended as such or not. Actual LEGO lauching machanisms (zamor spheres launchers, for example) can be quite dangerous and ...


The most important thing is to make you keep any swallowable magnet out of reach. This is potentially lethal if two magnets are swallowed and attrach each other from different part of the intestine, as unfortunately did happen to a kid a few years back with some other toy. That's why LEGO has completely redesigned train magnets to be completely encased in ...


The LEGO group pride themselves on their low product recall rate, which I believe generally only effects parts that break too easily or similar - often this is related to Primo or DUPLO components that are aimed at very young children. I'm not aware of a recall due to the chosen materials - as noted in this question the LEGO Group switched to their current ...


LEGO bricks should be safe for fish. Avoid using small parts that they could mistake for food. You also might be cautious on the paint, but I'm sure it's still safer than the paint used on the cheap stuff you'll find at fish stores.


A health risk with old, well used hand me down bricks is the possibility of broken pieces and foreign objects like staples, glass shards, old batteries, (loose magnets!) and stuff being mixed in with the elements. It's always a good idea to check through them before you hand them over to the next generation of builders.


Never fire bricks towards another persons face. There are certain sets that provide mechanisms to fire bricks such as the Agents: Gold Hunt set. The missiles are rubber tipped to minimise damage. If your school students are tasked with a project that involves projectiles I'd make sure they wear safety goggles, Especially if it involves non-lego parts or ...


If possible, give the kids large, rimmed trays (or even the lids from storage boxes) to keep their loose elements in. This will reduce the number of pieces that fall on the floor and get stepped, knelt or sat on.


Make sure the kids avoid separating pieces with their teeth. Give them some brick separator tools and teach them to use them. Sharing is very important! You don't want another kid bopping someone in the head because they stole their piece. If you don't have enough of a certain piece for everyone then don't include that piece. If using projectiles only use ...


Nothing really worse than the newer kits, quite frankly. Below 3 years old, they tend to explore what the world has to offer by putting small bricks in their tiny noses. for these reasons, an adult need to be there all the time brick toys are in use. If the bricks happen to be the adult`s toy, rigorously stowing them away when not playing is in order.


Don't lift too many bricks at one time. Being slightly older, I find a bag full of bricks can actually get heavy. I recently pulled a back muscle lifting a bag of 9,000 bricks. Hmmm, need to lift with my knees! Granted, most people won't encounter this problem, I'm just saying....


There is a list of recent recalls on the Lego site, so that's a start. It contains two items: A specific version of the IR remote, typically used for trains. A one piece toy truck, only sold in the USA.


The complexity of the model and the expected time to complete it will increase with the recommended age. Lower aged sets, like the Juniors line, feature builds that rely heavily on standard stacking and more basic bricks. As the age recommendation goes up, you'll see more advanced building techniques such as offset stacking (think stair stacking), studs ...


No, the LEGO Mindstorms EV3 is NOT waterproof. Any electronic product that is capable of being immersed in water will clearly state in the packaging/manual the level of water protection provided. This may be in the form of an IP Code: Ingress Protection Marking, classifies and rates the degree of protection provided against the intrusion (including ...


If you want to know how many bricks you'd need, there is some site to help you calculate it.


Old bricks might just be plain dirty. If your LEGO sets have been collecting dust on a shelve for twenty years, you might want to clean them off first.
