How to make a 125mL round bottom flask

In need of a container to boil some copper sulfate, the first thing I thought on was a light bulb. In this instructable I will show you how to turn a light bulb into a flask.

-=sorry, before it said 150mL but its 125mL=-

-=light bulbs are fragile a susceptible to thermal shock and will crack if not heated properly=- 

Step 1: Gut the bulb

Using a pare of pliers rip out the solder from the bottom of the bulb. Next break the purple glass insulator. Nest using a screw driver, stick it down the bulb and break the insides and smooth it out. If the bulb has the white powder in it then just wash it out with water a few times and wipe it with toilet paper or a tissue to clean any residue left behind. 

-=theres a small glass tube inside I think used for evacuating the air, if you save this and melt down the broken edges a little you can use it as a mini test tube=-

-=The purple glass is very sharp as well as the rest of the glass to be careful, you may want to put gloves on for this part=-

-=leaving the metal base is optional but recommended, it will break easier if you remove it and cannot be clamped onto a stand=-

But where do you get an incandescent lamp these days???

[Electroinnovation]

Home Depot, Lowes, your basement, basically any home improvement store.

everywhere

Nah they've been phased out in favour of compact fluorescent lamps - some lame brained greeny scheme...

There are a few decorative types available but wouldn't be suitable for this purpose.

You can still buy them and you can find em if you know where to look.
