To prevent any smoke from seeping under the door, you should roll up a towel and lay it out in front of the gap at the bottom of the door. Make sure that the towel extends from end to end of the door and that it is pressed close against the gap. Taking a shower is a good excuse for spending lots of time in the bathroom and the steam will also blend with the smoke and help to cover up the odor. The sound of the shower will also help to mask the sounds of a lighter striking or of you puffing and exhaling smoke.  You may also want to play some music on your phone to provide an extra layer of sound protection. Make sure that you actually take a shower (or at least get your hair wet so it looks like you took a shower) or people will be suspicious. As you smoke, make sure that you direct your smoke towards an open window or towards a vent. You may want to check out the window first to be sure nobody is outside who might see the smoke escaping from the window. If you have time to actually take a shower, then make sure that you shampoo your hair. The aromatic qualities of the shampoo will quickly fill the room, making any smoke odors difficult to detect. You can also pour a bit of shampoo into the sink and fill it up with hot water if you don’t have time to wash your hair. After you are done smoking, empty your pipe or toss the remains of your cigarette into the toilet and flush them. Do one last check of the bathroom to be sure that there are no ashes on the floor or anything else that might signal to someone that you were smoking in the bathroom. Try to get an air freshener that has a strong scent and that also neutralizes odors. Spray lots of air freshener before you exit the bathroom. If you do not have any air freshener on hand, then body spray, cologne, or perfume can also work to cover up the smell. Spray it on yourself and around the bathroom as well.

Fasten your chain onto a set of two spokes, over both spokes, where they cross, so the chain won't go sliding down the length of a spoke. Aim to form a cross (see the image for guidance). The chain should slide easily through the hook and be suspended from the ceiling.  If the chain is too long after hanging it, use steel cutters and snip the chain, allowing for a full link to be available for hanging.

Slide the end of the chain on the wire spokes of the bike wheel. Distribute each chain evenly across the wheel. Slide the hook through the loop and attach the chain.


You want to drill slower when you are drilling into hard materials; you can find charts online that provide recommended drill speed for different materials, including glass.  Chuck a small bit into a variable speed motor drill. Make sure it is secured tightly. It is best to start with a bit maybe about 1/8" or 3/32" in size. You only want to create a dimple in the glass at first. Then, remove the cardboard or tape and drill faster, at about 400 rpm. If you drill too fast, your drill bit could cause burn marks around the tip. If it seems necessary, swap in a larger bit to enlarge your initial hole. The first hole is a "pilot" hole. It will guide the subsequent larger bits as you work your way up to the size of your finished hole When drilling glass, you should keep the drill at low or medium speeds. When you are close to breaking through, slow it down even more because this is when the glass can be the most fragile.  If you press too hard on the glass with the drill, you could crack it. Hold the drill perpendicular to the glass so that you prevent chipping. You'll want to use lighter pressure if you're new to drilling to make it less likely you make a big mistake.   Another approach is to drill half way through, flip the glass over (carefully) and drill through the back side of it until you meet the other hole in the middle. This is very important. Pour a little oil or water on the area that you are drilling. Water is the most common coolant used on drill bits. You will need to use more coolant if you are drilling a harder surface. The coolant will keep the drill bit or saw and glass lubricated and cool. If the glass gets too hot while drilling, it can crack and break.  Coolant should be applied both before and during drilling. You could put a bottle with water in it and a small hole in it at the drill hole. It will trickle out and onto the hole as you drill the glass, cooling it.  You could also spray a mist of water around the drill bit instead to keep it lubricated. Again, remember to be very careful of electrical cords and water. Try putting the water in a squirt bottle and apply it as you drill. If white powder forms as you drill, you should apply more coolant, and slow the process down. You could also place a wet sponge under the glass as you drill to act as a coolant.Or you could cover the glass with a small amount of water before drilling - basically put it in a shallow water bath in your container.

One-sentence summary --
Start drilling at a very slow rpm. Lighten up the drilling pressure and speed even more so when the drill tip is close to breaking through the glass. Use coolant so the drill bit doesn't get too hot.
