I built a bottomless pit several years ago based on some of the tutorials on MonsterList. But I never liked how incredibly heavy it was or the fact that when I picked it up the bottom would fall off. It eventually decayed and needed replaced so this is my modified version.

These are the basic steps I used to make it. I am not giving detailed instructions. This is pretty easy to figure out. Mine was based on a 24 X 24 inch piece of glass which I already had.

First I cut out four walls all the same size, each one a little over 24" wide to accommodate my glass. Then I added 1x2s to the bottom of all four, and the sides of 2 of them. I left a gap at the bottom for the glass to slide into.



Then I cut styrofoam that would fit into each panel. At this point you can assemble 3 walls. Leave the fourth off for now.

I drew out where I wanted my lights to go, sprayed some great stuff on it to make it look more rocky, or fungusy, and then used a dremel to make a track for the lights to sit in.

I took a blowtorch and melted the styrofoam enough to get rid of that smooth cardboard look. It is hard to tell any difference in the pics other than it is now brown, but in person you can see the depth of the burns. Then I painted it all red. I will add more colors when I am done.



Then I put some Great Stuff foam in some areas of the light track and laid the lights into the track. As I pushed them down some of the foam oozed out around the edge filling in some of the gaps and helping to hold the lights in place. Then I went back and added some more Great Stuff foam in a few areas to break up the solid line of lights.



More to come next Tues. I am waiting for another set of lights.

You are welcome Joisey, and I don't see a like button on any threads. I thought there use to be one.

I finally got my lights and some time to work on this.

After you have installed all your lights go back and cover them with a thin coating of great stuff. I discovered this will give it a much nicer and more subtle effect when they are turned on.


Finish painting your foam. Let me give you a really important painting tip. As you can see from my finished effect photo, no one can see what color you paint the inside. As you can almost see, I wasted a LOT of time putting a nice paint job on mine. Just go ahead and paint the inside red or brown. Since I used orange rope lights I put a light coat of orange spray paint on the foam covering my lights so the color would be enhanced.

Next, slide the mirror piece into the bottom slot on your box. Then you can put your fourth wall on. Have fun with this step. It is not that easy. Be patient and if you can get help, do. I don't have pics of this step as I could not put the glass in, cuss, throw stuff, AND take pics all at the same time.

After your wall is screwed in place I suggest laying your box on it's side and taking an air compressor and blowing any junk out of it. Any trash inside can ruin the effect.

Add some Great stuff to the outside if you want. Then paint it when it is dry.


After you are done with that you can set your top mirror in place. It should just set right on top of the foam and corner supports as you can see in the pic above. I used a regular piece of mirror for the bottom. But for the top piece I used plexiglass with one way mirror tint installed. Given a choice, I would recommend plexiglass for both pieces for two reasons. 1) Glass or mirror is VERY heavy and 2) they are very breakable. The mirrored film works great.

Hey everyone, thank you so much for the encouragement and compliments. It really makes me feel great.

Waldiddy:
1) I got my mirror film at Home Depot for $25 a roll. I change my film each year to make sure there are no scratches or lines for a nice clean effect. A roll lasts through 3-4 changes. It is not hard to apply. Follow the directions exactly as on the product and it will be easy enough. Use the spray recommended, liberally. The mirror film is only applied to one side of the plexiglass or glass. You could use this on the bottom as well, as long as you have the mirror side facing up. I used a real mirror because I happened to have one.

2) Yes, it is sturdy enough to tilt on it's side. That is how mine will be displayed. Here is a picture of one I built in 2006. It is tilted on it's side and rests in a pile of hay. You can tilt it sharper if you want.


3) It took me about 2 days to build this. The Great Stuff foam actually dries pretty firm in a couple hours, you can touch it or paint it even sooner.

Daphne: The mirror on the top is a one way mirror. You can see through one side but not the other. These are often mistakenly called 2 way mirrors which would indicate that you could see through both sides. That is called glass :). The one way mirror is installed with the mirrored side facing down. The regular mirror in the bottom of the pit is installed facing up. When it is dark outside and the light is on in the pit it allows you to see through the top one way mirror down into the pit. The bottom mirror reflects everything it sees back into itself, including the one way mirror. That is kind of a confusing explanation, huh? Sorry I am not better at explaining things. Hope this helps.

Thanks again for the nice comments and questions.

LOL Daphne, You kill me. That is hilarious. Hmmmm, hide them in the bag with the new set of screw drivers you just knew he would love. hehehe.

Waldiddy, No, the box does not get more narrow. It is equal on all sides. The effect is created by mirrors. The mirrors just keep reflecting themselves so they seem to go on forever. If possible, get a mirror and hold it in front of another mirror. Size doesn't matter (not here anyway). As you look into the mirror you will see the other mirror repeatedly reflected back so it looks like dozens of mirrors. Same principle here.

Good advice Daphne, I am glad you didn't actually try that tape thing first. LOL I wish you had gotten pics of the hubby's new expression. Maybe we could have fashioned a prop after it. hehehe

Wow, Daphne. You are just a fountain of informative what not to do's. Good thing you thought everything through so we could all operate more safely. :)

The first time I bought mirrored film (around 2005 or 06) it came with the solution, a small utility knife and the squeegee. So I went and bought some for this project and assumed it came with. Glad I stopped to read the box. I noticed it didn't say it on the box. Darn, you pay$25 for something it should come with all that. That solution is costly. I used mine on plexiglass and it works great. Except a few years ago I got a dried stain on the glass and now the plastic doesn't want to stick there and makes a crease. It is not real noticeable during display so no worry here.

And again this year it was a very popular prop. The kids and adults both love trying to figure it out. They guess mirrors but not sure how they work. Some kids think it is really a long tunnel. Thanks for the great comments.

Hey Daphne, I never answered your question...sorry. And the answer is NO. It is very dark in my neighborhood, so I have no problems with lights ruining my effect. Sometimes you can see your own reflection in the top but that has never ruined the effect for anyone or diminished it's coolness with the kids. Since I let my ToTs get right up to it they touch it anyway, so they know there is glass on the top. They are still amazed at the effect. But if the outside light is overpowering the inside light your effect will be ruined. Let us know if your ideas worked in case anyone else has that problem.

Daphne, The tent sounds like a great idea. I had mine at the end of the hallway of my inflatable haunted house one year. It looked great and also made it so the kids HAD to walk past it so it didn't get overlooked. I hope you can find a solution to the light problem.

Debbie, I don't know what a sonotube is, but I have never seen the design you described. Sounds like it may be a pretty unique approach.
