The Four Tubes

[aquaMat]

@ Scout:

Thanks for the nice words !!

As for your question:
You should simply try to get back to

safe ground

(e.g. the top of the column that has the

vibrating brick

in it) and from then on continue your way upward....

Does that help ?  (I'm not completely sure I understood your question correctly !?)

@ arevn:

Addition to my reply above:
In the meantime I have tried to duplicate your behaviour to find out what your problem might be.....  I sent you a PM about it.

However, starting with the BLUE tube is definitely just as possible as any other order.
