I Built a LEGO Water Park Rapids Ride!

I built a working LEGO water park rapids ride using LEGO and LEGO Technic!
Sitting alongside rollercoasters and other amusement attractions, river rapid rides are a huge amount of fun!
The ride utilises 8 large power functions motors and achieves a measured water output of 1800 litres per hour via its 2 centrifugal pumps!
The ride features a course length of 2.6m from drop-in to lift hill with 2 ride vehicles.

With that pump, you definitely need a longer version of that ride! 🙂

[@tigertut2410]

Absolutely

[@DaRip74]

semi agreed, its the right length to add in 1 more boat becouse another can drop when the first is half way through, just have to get the lift timing.

[@jbponzi1]

So many questions running through my mind as you were building it, first was "legos are not water tight how are you..." no problem doesn't matter. Then "maybe a round ride vehicle similar to other rapid rides where there is no front so you don't get stuck" again doesn't matter, no problem. So yeah, this was super awesome. My ONLY worry would be my expensive motors and battery packs getting wet as water wicks it's way up those shafts some how.

[@dsihacker01]

Iirc, motors are naturally water resistant, and only the battery box is an issue

[@paul_ko]

@@dsihacker01 Naturally water resistant? Maybe if it's distilled, non conductive water...

[@Amelie12]

not water resistant, the contacts corrode and while powered they short itself what would cause battery to lose to much energy quickly.@@dsihacker01

[@derSonnige]

I love the Idea to build everything from Lego but in the case of Water pumps it might be just a good Idea to use an aquarium Waterpump. Lifetime price and especially safety might be better in that case.

[@someguy4915]

@@dsihacker01Only if it's distilled water, normal tapwater will just corrode the entire motor. Even with distilled water, it will clean out grease/lubrication from the bearings which will seize up the motor.

[@bizarrefruit9133]

On behalf of 8 year old me, thank you very much. All of my experiments with lego boats in water failed miserably and I came to the conclusion that unless I wanted to seal them, I was out of luck. This is such a clever way to overcome the problems of the material; any lost water returns to the reservoir and the flow rate of the pump overcomes the losses.

[@BuilditwithBricks]

My pleasure!

[@germanochoajr6400]

The fact that they always ended up facing backwards in the end, made me chuckle

[@terribletablevods862]

i suspect it has to do with the center of gravity being slightly toward the back due to the riders

[@LuminaryChess]

Can we all just appreciate the amount of effort put into making this? :)

[@BuilditwithBricks]

Thanks! It's one of my favourite theme park ride types. I had always wanted to re-create it in LEGO and I'm glad you enjoyed it!

[@christopping5876]

What a very clever impeller! I agree with others. It does need to be longer and maybe a few more rocks and bumps in the rapids. Great idea and implementation.

[@furgel7717]

This is really darn cool but words cannot describe the amount of anxiety I feel seeing electrical components this close to water only being seperated by poorly isolating Lego bricks.

[@Kharnellius]

It’s only batteries. Can’t even get a shock let alone hurt.

[@furgel7717]

​@@Kharnellius That's not what I'm worried about, Lego is damn expensive is what I'm worried about!

[@flashchrome]

I don't know why but I smiled the whole time. This was such a fun project to watch. Let's take a ride! EDIT: I can imagine this being even cooler in the dark with lots of running led's, turns, switches and stuff... Endless fun

[@rochelimit55555]

And forest!

[@PaulFisher]

This is very neat! I wonder if you could get even more efficiency out of it by adding some curves to the pumps, so that the walls of the impeller are closer to the blades, and guiding the output so that it doesn’t slam directly into a right angle.

Thanks so much! It’s great to see I can inspire others to enjoy such a wonderful hobby!

[@woaminibricks]

An interesting creation. I have also made many water pump from lego, but i think I need to learn more from you

[@Orionrobots]

This is an awesome build. Interesting to observe that the chain lift mechanism possibly represents a main capacity constraint, with the number of dingy's being 3 on the chain, and the chain speed being slower than running the course. It's not a thing I thought of with those rides, but probably translates to a constraint on real-world rapids in large theme parks. Perhaps a few slower chain lift sections are used to space capacity along the rides too.

[@topgun9686]

very kool though id probably use like the yellow raft pieces that actually float for the ride boats

[@brandonjohnson9084]

Would be fun to see some floor texturing added. Like those flat Lego plates. Just enough to make the water rise and fall in certain areas!

[@BuilditwithBricks]

Hi, thanks for the comment! I completely agree with you - I considered this during the build but I will have needed a deeper channel with more water flow for you to be have been able to physically see the 'turbulent' areas you mention. Perhaps in a future video I could improve the pumps, create more flow and try this out!

[@brandonjohnson9084]

@@BuilditwithBricks that would be so cool!

[@user-qs2ln5jp5o]

900 liters for that size pump is usually quite bad but the fact that it is a lego pump and it's pushing that number is damn good

Love it. Not going to lie, it looks like you've found the secret to making water flow slightly uphill. Please share your findings with the "scientists".

One of my favorite things to do with Lego is build functional models. They don't include mini figs, and are purely meant to work with the crank of a handle. I especially like what you've done here, where the Lego works with water. I love to see stuff like this!!

[@Manabender]

My first thought was that there's no way lego connections are watertight. And indeed I was right; around 1:14 you can see water leaking from between bricks. But the more I watched, the more I realized you accounted for this from the start. All the water finds its way into the large "bowl" that everything is contained in, one way or another. Brilliant!

[@BuilditwithBricks]

Thanks for the comment and support! Glad you enjoyed it!

[@alicat398]

Brilliant. If boats were circular it would be a better story as direction is not an issue and boat turns look natural.

Hi, thanks for the comment, yes it sits in a shallow pool - just like an actual rapids ride in a theme park operates. It recirculates water in an enclosed basin!
