| I have found that suspending from black carpet thread is usually the best solution. You can super glue the thread to the inside of the neck of a bottle or better yet cut a disk that fits in the neck with a hole in the center. The thread can be sprayed with dulling spray and unless the background is very light and a backlight reflects on the thread, you seldom have to do any rig removal to get a perfectly clean shot. You can also hot glue 1/4 20 T nuts The Hillman Group 2511 1/4-20 x 5/16 x 3/4 Inch Brad Hole Tee Nut, 13-Pack to the side of a bottle or anything else and attach a threaded rod held by a Gobo Head. Using a suction cup on a bottle will give you a fairly large funny looking spot on the bottle that will be hard to disguise in post. Hot glue will easily hold two or three pounds with a 1/2 inch dab. Super glue works extremely well. You still have to make sure that the shear loads are not too great and make sure the torque load (bending load) does not cause the attachment to fail. If you really must use a suction cup then there are a lot of household options on Amazon: M4 Strong Transparent Screw Suction Cup Hook 5 piece/pack,Cap Nut I would not trust them with much of a load. Hope this helps. Super glue, hot glue, black carpet thread, dulling spray, 1/4 to T nuts and oval nuts have been in my Grip kit for more than 40 years. They are as indispensable as Black Wrap. Hope this helps. Rick Gerard DP/VFX Supervisor Northern CA |
