Fill and freeze them for ice blocks,if you like fresh brewed tea,soup etc. fill and freeze.
Stop using them and get filtered water. Sorry, I'm not trying to be negative.
I bought a reverse osmosis machine from Lowes from $145.00. It has three filters and makes even the most awful water taste good. We refill the water bottles and keep in the fridge. I work outside during the summer and drink 10-12 bottles a day. The bottles make it convenient.
Since you have great tasting water, I would suggest you purchase one or more reuseable metal water bottles to save the landfills. These bottles keep the water cold for hours. Each of us has one and we take them with us wherever we go. Glad you are keeping hydrated.
I use them a vase. Take label off. Fill the bottle to half with water. Add marbles, glass stones, etc. (dollar store) to stabilize bottle. Wrap top with 3/4 nice ribbon, fun tape (dollar store). Use any flower, from which you can break off sections, such as carnations, hydrangeas, etc. I love to use three bottles on the table. People can see over each other. You can also use some paints to add interest - all the way up, partially, etc. I like colors with a small touch of silver for darker colors, gold for oranges, yellow for organce colors. Great for gifts, especially at holidays for friends, officemates, neighbors. Recipients won't feel obligated to give you a gift or an equilly expensive gift, such as pretty candles. You can also use some paints to add interest - all the way up, partially, etc. Recycle any unused bottles.
Use a water filter, like PUR, and put into larger other separate bottle. Make sure the container is BPA free. I put in insulated bottles/ coffee mugs and put in refridger. Then make a another filtered water for home. Stick in fridge. I like filtered ice cubes.
please get a Tervis and stop using them. Most end up in the landfill or ocean
Wrap it in durable fabric, secure each end and let your dog play.
if you can find old humming bird feeders that they will fit use as feeders or make your own feeders lots of fun
With the number of bottles you are going through, you are not going to be able to repurpose them all. I sincerely suggest a water filter and reusable metal or plastic bottle. It is a crying shame to trash all those bottles.
I've seen wonderful greenhouses made out of recycled water bottles. There are other ways they can be used for everything from automatic plant watering to bird feeders & edging for gardens.
if you are not planning on recycling them directly into your recycle bin then you could cut the tops off and use them for seedling starter pots and the tops can be placed into the garden next to existing plants and you can water directly into the drinking spout so the water goes directly to the plant you are watering not all around the plant.
Irene is right, you probably have more bottles that we have suggestions. However, there are some practical uses. For a large planter, you can use them as a filler at the bottom in order to use less garden soil. You can also use them for packing things you need to ship - they are light weight and will act to protect your products. Also they are used in the garden as a watering method and potted plants when you are going to be away for a few. Busy hands are happy hands. I'm sure you can find lots of crafty ideas, maybe look to youtube and do a search. That ought to take care of a few. Otherwise, the recycling bin is your best bet where others come up with their own ideas for more plastic bottles.
Instead of buying bottled water, get a water filter system and a thermal coffee cup, it will keep your water cool, I use a stainless steel one made by Contigo. This will cut down on having "what to do with the bottles".
Refill them with the filtered water that your fridge dispenses.
Stop buying water bottles. The production of these bottles is devastating to the environment - not to mention driving water from the source to you and often this water comes from sources that are already water deserts like California - contributing to the water crisis. Plus these bottles are loaded with BPA which is very harmful to you and reusing them for planting or other things breaks down the BPA and leaks it. Use a glass or steel water bottle and refill it.
I agree with those that are suggesting you stop buying water. You are paying double; water supplied by your community and, the bottles of water. As we all have been told, plastic bottles have a non-limit lifespan. I hope you at least recycle these empty bottles.
