Review of Klutz LEGO Crazy Action Contraptions 2

One thing that really bothered me when I starting building LEGO Technic models is the lack of bricks and beams. So on my race to build a good supply of parts I bought Klutz Crazy Action Contraptions (£8 on Amazon.co.uk) because it has lots of gears and axles and what the hell, because the book looked so good.

Now that I have read it ( it is really a short one ) and build most of the stuff I have an opinion about it: Lovely book!.
Don’t expect something utterly complex here, it is a LEGO Book with stud bricks and gears that let you build little crazy machines using rubber bands ( also included on the book ).

Here are the main experiments that the book features.

The Beaker Blender 3000

This blender is a really cool way of showing how gears works, and it really enlight you about the torque/speed stuff. You need to apply a lot of power to the handle and the blender will move awfully fast.

Annoy-o-matic

Did you ever want to break a LEGO gear? Well, this is a fast way of destroying your gear’s teeth. But it does a cool sound… think of it as a trade-off…

Squeezeclaw grabber

This is a very simple claw but it really inits you into a powerful mechanical construction. Anyway, it doesn’t really works because you can’t retrieve objects using it. Just grab them.

No Donkey donkey-cart

This is the most lovely construction of the book in my opinion. I just love the simple idea behind it and how well it does run. As I said: Lovely.

Art-a-maton

Surely my expectations were high on this one, or perhaps it was my pen. In any case this has been the construction I have enjoyed less of the book. I built it and I couldn’t stop thinking “What the hell!?”

LEGO Launcher

If you don’t have kids around, this is the best way of losing your LEGO parts. As I have already two, I manage myself quite well into losing bricks and plates… but anyway, it is impressive to see how far the piece can travel.

Wall rocket Launcher

At first I didn’t understand what this model was about. But once I pushed it agains the wall I saw it. Quite clever and definitively fast! It is almost invisible on the video.

Battle-top-spinner

This construction uses rubber bands and gears to create a spinner using the big grey gear.

Supercharged Speedster

This is the reference model of the book and perhaps the most complex. Just remember to add the rubber bands to the wheels or power won’t be transmistted to the ground. That’s fast!

Zipline Runners

My eldest kid loves this one. I build the base using some LEGO Duplo parts and then build the zipline runners. It is pretty simple but kids love it.

Tennesse Time Killer

This one is amazing! It is a great way of teaching physics to kids. First thing my son asked me when he saw it was where the batteries were?.
Just using gears and rubber bands you can have this one moving for minutes, no joking.

Watch all of them in action is this video.

So what do I think of the book? A Must-have book for any LEGO fan really. Quite fun and enjoyable and simple enough for a child to build on his own. Also a great (cheap!) way of getting not too common parts.

    Crap crap crap crap crap. They are all too hard to build and things pop out everywhere. It is so bad I just feel like chucking it in a bin. This product can go die in a hole.
