Article: You will need at least 65 metal bottle caps, acrylic paint, fine paintbrushes, adhesive craft magnets, and paint sealant. Be sure to have thick cardboard and a hot glue gun on hand. They may also be required. You may also use spray paint as a first "primer" coat instead of slowly painting each by hand. If the magnets are too thin, they won't be able to make contact with surfaces and stick properly. Glue squares of cardboard to the inside of the bottle caps if your magnets are too thin. Lay down a solid base coat and let it dry before adding details. Paint at least 31 caps one color for the dates of the month. Paint at least 7 caps a second color, one for each day of the week. Paint at least 12 caps a third color for the names of each month. For special occasions, you can paint the remaining caps additional colors. Or, you can reuse one of the three basic colors. Use a fine brush to paint on your labels. Number each of your date caps 1-31. Write abbreviations on your month and day of the week caps. Paint symbols for special events (like balloons for birthdays or a heart for Valentine's Day). Without the sealant, acrylic can chip away. Wait for the paint to completely dry before sealing and then wait for the sealant to dry before moving on. A spray on sealant will take less time, but a brush on sealant will work fine, too. Cut the magnets into appropriate-sized squares. Remove the tape to reveal the glue side. Press the sticky side of a magnet either into the inside of each bottle cap or on top of the cardboard. The best thing about this method is how easy it is to change how the tiles are laid out. You can spread your calendar over a whole freezer or carefully line it up inside a locker. It's also incredibly easy to transport. Just put the pieces in a small box or bag, and you can take them anywhere.
Question: What is a summary of what this article is about?
Gather your materials. Make sure your magnets are thicker than the inside of the bottle caps. Separate your caps into at least three different groups and paint them different colors. Add details to your caps. Apply the paint sealant. Attach sticky magnets to the bottle caps. Arrange your calendar however you want.

Fill a 5 gallon (18.9L) bucket with sand, rocks, concrete, or even water. Use it to do curls or attach two of them to a bar or board and use as a bench press. Take 2 packs of 6 bottles each and duct tape them symmetrically to an iron bar you can grip easily. This barbell will be good for any exercise you do with a barbell, like lifts and presses. If these 2 packs are too much, don't use half filled bottles. Half-filled bottles will slosh around and shake the bar. Instead, tape individual filled bottles to the bar. If 2 packs aren't enough, use four or six packs of bottles taped to the bar. Alternately, tape individual bottles to each end of the bar. First line them horizontally along the bar side by side, then stack them on top of each other. Make sure to leave plenty of room for your hands to grip the bar in wide and narrow grips. The taping must be functional. Make horizontal, vertical, and diagonal rounds to wrap the packs to the bar. Tires are used in many workout and bodybuilding routines. You can add additional weights to regular tires when doing workouts, or you can go to a junkyard and find tractor tires. Flipping them and tying a rope to them to pull behind you are only two ways you can use a tire as a weight. Slosh tubes are long plastic tubes filled with about 40 pounds of water. But the workout benefits come from the uneven, sloshing water, which makes you use muscles as you try to keep the water balanced as it goes from one end of the tube to the other. You can make your own slosh tube with a PVC pipe. The pipe should be about 4 inches in diameter and 9-10 feet long. Place a cap on one end, then fill the pipe halfway with water. Cap the other end. Sandbags are similar to slosh tubes in that they are unstable, shifting weights that require you to engage more muscles. To make an easy sandbag, fill 5 or 6 gallon freezer bags with sand. You want the sandbag to be around 50 or 60 pounds. Double bag the bags so they don't break, and then tape the end. Place the bags into the duffle bag. Zip up the duffle bag, and you are ready to work out! An alternate way to make a sandbag is to use an old army/navy rucksack or canvas laundry bag. Use contractor garbage bags to fill with pea gravel. You can fill them with 10, 20, or 25 pounds. Fill 5 or 6 bags with gravel, and secure them with duct tape. Add them to the bag until your desired weight. Add and remove bags of sand or gravel for different weights. Use a scale to determine how heavy the bag is before you start working out, and add or remove weight accordingly. If you don't want to change the weight, you can add the sand or gravel directly into the bag. You cannot easily remove the weight or add weight if you do this. Make sure to leave some room in the interior bags so the sand or gravel can move around. If you are adding a large amount of weight, use a sturdier duffle bag.
