The Aperture Science Simple Test Chamber

This is The Aperture Science Simple Test Chamber. Its... a bit of a long name, but we couldn't find a better one. Anyway, you'll find that this test chamber is completely normal and simple. It may seem difficult, but it really isn't. Just walk around and try to find all the materials you need to get to open the door. That's all you need to know.

Oh wait! Ask your test supervisor for some Bottled Water. You might get a bit dehydrated during this test so this is your opportunity to ask now.
...
You started the test already didn't you? Ah well... Just do your best.
