pouring liquid from a bottle is messy sometimes i mean the liquid spills run by the body of the bottle mouth, even for oils they just stuck on the bottle cap grooves. so there are bottle nozzles for these problems but they are hard to come by in my area and bit expensive to use. so i came up with this idea to make bottle nozzle out of scrap. u can use it for chemicals also coz i made it air tight way. Even it can used for liquor bottle

Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Instruments
soft drinks bottle
hand drill or electric drill
15/64 drill bit, its a good size for the insulin syringe
plastic glue gun
needle & thread
Step 2: Preparing the Syringe
take the plunger out from the syringe. dont throw the plunger. coz we will need the rubber of the plunger
Step 3: Preparing the Bottle Cap
i used a drill bit 15/64 in a hand drill u can also use electric drill. i used hand drill coz here there is no need for power just some swing of the hand drill is enough.now make a hole in the bottle cap. but dont make the hole as shown in the pic it gives a everted edge in the other side which is tuff to clean and i want to push the syringe from that side so gives me trouble. so its easy if u just make the hole from inside of the cap so its much easier
Step 4: Attaching the Syringe to the Cap
now insert the syringe through the inner side of the cap, but don't push the whole syringe keep it at the middle as shown in the pic. now put some plastic glue at the junction of the hole and syringe to make it air tight. now push the whole syringe up-to the last end before the glue gets cold and hard. Now keep the syringe end for some time to settle the glue and the end point of the syringe. Now the syringe it tightly fixed with the cap plus its air tight.
Step 5: Almost Finished
now u r almost done. attach the modified cap to the bottle and test it with any kind of liquid. its simple cheap but cool.
Step 6: Finishing the Air Tight Mechanism
now take the rubber out from the plunger. and use it as a air tight cap for the syringe head. i bind a thread using needle and attached with the syringe body so it wont get lost.so thanks hope it helps
