Highlighter

Water Bottle

Highlighter(s) and Water Bottles?
I don't believe that there has been an actual market item that combines both highlighters and water bottles, but you never know.
-The first idea that came to mind was to make highlighter color water packaged within the bottle. The water could come in all different colors pink, green, blue, orange, and purple. I think it would be very eye appealing to consumers and fun. I'm not sure to the degree consumers would like the idea of water being a bright illuminating color versus the historical clear it is. They might not view the water has healthy or beneficial. On the bright side this could be a bigger winner with kids, they could view the product as new, fun, and at the same time good for them.
-The next idea is a spin off of the first one but instead just have highlighted water bottles versus highlighting the water. This could be a bit more receptive then the first idea because you won't be affecting the water just the bottle. And again kids would like the colorful bottles as well as other age groups that find the new color bottles as cool and modern.
-You could start selling highlighters within water bottles, but obviously there wouldn't be water in the bottle. You could fit any amount of highlighters within the bottles as long as the bottle was big enough. My main concern would be how would the highlighters come out of the water bottle, perhaps some alteration to the size of the cap?
-You could make water bottles into a shape of a highlighter and marketing them like that. Image having a 12oz highlighter in your hand with the same twist off cap (original version) and water coming out of it. There would be no alteration to the water just the bottle. I think this idea would be pretty cool, a huge highlighter that is water. Or you could keep the same idea for the highlighter water bottle and actually have highlighted water come out of it. Again you could have an array of colors to choose from to highlight the water.
-Stemming from the same idea above you could make water bottles a bit smaller and just have one time use for it. Lets say the highlighter water bottle only holds 3-5 oz. of water for a one time use. In a sense this is like the small liquor bottles. The only problem would be that I'm not sure how many people just want one sip of water, you would have to have multiple 3-5 oz. highlighter water bottles.
-Vice versa why not make highlighters in the shape of a water bottle. Obviously the water bottle size would be brought down to a substantial size. So in essence you would have a lot of water bottles that are highlighters but again without actual water. This design would require some alteration within the bottle because it would have to hold the writing tip of the highlighter and ink inside it.
-A more rational combination would not to actually create a new product but to bundle the products with a manufactures agreement. Lets say every five water bottles in a 24 pack would contain a highlighter attached to it. And for every 5 or 10 highlighters bought you get a free pack of water bottles. This is a lot more promotional based but could be a big hit during back to school for students.
-You could make the color of the labels and caps of water bottles a highlighter color. This would make your water bottle "pop" and stand out in the aisle.
After a couple of days of trying to think of new ways to add, transform and create a new product with these two I have come to an end. I think the ideas above are really unique for the most part and I really surprised myself of all the ideas I thought of. It would be interesting to see one of these ideas in action to see if it would really work.
