So you decided to read this So heres an example of a (Not so) nice chamber entrance you can play it so you can copy the entrance. http://steamproxy-script.pipiskins.com/sharedfiles/filedetails/?id=966486218 Now if you tried it then you dont really need to read this section.
Now if you did not look at how the entrance is then heres some advice.

First: push back the entrance by 4.

Second: When you do that then put a trigger at the end i suggest you put a door there also make the trigger a trigger mutipule(Correct me in the comments).

Third: Then put in the Gel trigger on tile number 2 make it any type of Gel you want.

Forth: You are now finished but put in a light strip on tile number 3 to light it up.

Now you that you read the first guide now you can read this one.
Push your exit and viewing station back at the end so you can build! It your way. PS DO NOT USE THE SCAFOLDS THEY WILL NOT FLIP!!! PPS I made that mistake once to.

You have now made your chamber but.
Put a door covering the end with a fizziler in the end section with a light strip it should be 2 tiles back.
You have now finished this guide i hope you found it really helpful. Heres mine check it out by clicking this link. http://steamproxy-script.pipiskins.com/sharedfiles/filedetails/?id=966486218Good luck on createing it goodbye!

If you want to finish this then read this part put in flip pannles connected to a trigger to make it look like it was not recycled but thats optional And another time Good luck!
