Hi Guys, what you are looking for can be found at any auto supply store, they are used to add acid/water to batteries, not so commonly seen in this day of sealed batteries, I bought two in case they become hard to find, you'll throw away your turkey basters when you get one of these, the bulb never detaches, I use mine mainly to blow detritus off my monti's , but as mentioned it has many uses, they don't come with clear acrylic, that is easily modded if desired, the rubber bulb is what makes these so great, so save on the shipping and waiting time and head to schucks or pep boys........
