This is by far the toughest trophy in the game as it requires you to get a gold medal in all the levels. There are 8 worlds with 6 levels in each and to get a gold medal you need to complete the level quickly while not losing too much liquid.

I have recorded me getting gold medals on all the levels. This should help you a lot as you can see how to go about some of the more difficult levels:

Watercourse:

Nursery:

Laboratory:

Human Body:

Sewers:

Rocket:

Foundry:

Nuclear Power Station:

You will be rewarded this trophy for completing all 48 levels. You do not even need a medal, as long as you have reached the finish on all the levels, you will earn this trophy. You will get this while going for "Gold Rush".

As you progress through the game you will unlock items to use in your Laboratory by getting medals on levels. One of these items is a duck! You will unlock the duck for getting a gold medal on Dionaea in the Nursery world.

Once the duck is unlocked you need to go into your Laboratory and place the duck into the environment, simulate it so that the water touches the duck then the trophy will pop:

This is quite tricky. I finished many levels with the level being on red but it seems you need to get it perfect! The level must be right at its limit and if it is half way up the red line, it will not be good enough.

Your best bet is to forget about this trophy and it is very likely that you will just get it. You will play levels over and over while trying to get gold medals and you are bound to do the requirements for this trophy at some point.

There are a few levels where you can purposely lose liquid and try to get it to the right level. You can then complete the level for the trophy. The video shows how I got it. Take note at the results screen, you will see that the two numbers are the same in the calculation. If these numbers are different then you will not get the trophy as it will not be the exact amount of liquid:

Two thirds of the way through the level Wastewater, you will come to dead end waiting for a timer to tick down before you can continue. A door will open and beyond that there is a high path and a low one. The high path is a shortcut and this is where you need to go for this trophy.

Watch the video to see me do it. I stayed as far to the left as I could and then when the light turns green, I moved forward and jumped from the opening door to reach the shortcut:

During the level "Bulb" you will need to release and then use bulbs in order to progress. The second bulb requires to be droped onto a platform in order for you to continue. To get this trophy you need to drop the second bulb without any liquid going with it!

The video shows one way of doing it pretty easilly. I do not have enough evidence to say that this trophy is glitched but I am certain I did this the first time I tried and did not get the trophy. I am sure no liquid dropped so there may be a possible glitch. The solution is to do it again if you do not get the trophy:

This can be done in one of two levels. The liquid is explosive and will explode on impact if going at high speeds or dropping from height.

You can easilly do this on the level "Kieselguhrs" in the world Laboratory. There is a part near the beginning that you can use to release small amounts of liquid. Release a small amount and let it go off screen for it to explode. Do this ten times and then finish the level for the trophy:

The Slightly acid level is on "Human Body". You will see some yellow cells aong the walls at some parts of the level. If you touch these you will trigger nausea. You need to make it through this level without touching any of the yellow cells:

In this level you are inside a glass ball. If you do a jump or crash into something the ball will crack and you will start to lose liquid. The more cracks, the faster you will lose it.

You need to make it through this level without getting a single crack. This can be easy if you take your time. There is no time limit but at the very end it is tricky to not crack the ball. You will drop onto a patch of grass but then that bounces you to the finish and the drop is enough to make it crack. I failed here a few times and it was annoying, I eventually did it by pressing at the right time as it landed. You can see how I got this trophy in the video below:

This is very easy. You will not be able to get a gold medal but you don't have to for this trophy. You just need to complete the level by only ever going in one direction. You will want to turn anti-clockwise as you will then be going the same way asthe liquid and you must not destroy this. You need to feed the electric into the object at the bottom to destory it.

It will always be the same so once you have learned how the electricity will come out, you will fly through this. Watch this video for more help:

This is tricky and the hardest part is not letting the liquid dry up. The liquid is in a pot and you need to complete the level without a drop falling out of this pot. If some liquid dries up then that is ok as it never fell out.

There is plenty of fire to help keep the liquid from drying up and you can watch me get this trophy in the video below:

You need to get this on the fireman level in "Nuclear Power Station". You are required to put out fire and once it is all put out you will complete the level. However, debris will be fired at you and this trophy requires you to complete the level without any of this debris hitting you. This is very straight forward as the debris doesn't really come that fast at you. When you see it you just aim the water at it and it will disappear. Watch the video below to see me get this trophy:
