DIY brine shrimp hatchery!

Just created this in an hour ago..

Items required:
- 2 big soda bottle, best without much groove so that the brine shrimp doesn't get stuck on the grooves
- 1 balloon stick (hollow ones)
- 1 2way connector
- air tube
- drilling tool

First, take 1 soda bottle and cut the top away to act as a stand for 2nd bottle as the 2nd bottle will be upside down.

Take the 2nd bottle and drill 2 holes, one preferably by the middle, in order to insert the balloon stick and keeping it straight. 1 could be by the side or on the bottom too.. But since I was drilling via manual drilling, I choose to drill the 2nd hole by the side as it is much thinner and easier.

Then insert the balloon stick and push it all the way in and touch the bottle cap. This is to ensure that the bubbles reaches the bottom and create movements for the brine shrimp egg.

Insert the 2way connector at the 2nd hole. You can choose to seal them but since I had it quite fitting, I am skipping the sealing part.

To use this hatchery, fill the bottle with the salt solution and brine shrimp egg, connect the airtube on the balloon stick and watch it bubbles!

When harvesting, unhook the airtube from the balloon stick and connect it on the 2way connector and watch the hatched brine shrimp being pushed out from the balloon stick. Of course, you have to add a tube to the balloon stick and collect the shrimps via a coffee filter bag so you could rinse your shrimps and feed them to your fishes!

Pardon for the lack of step by step photos. Forgot to take them when doing it. Will update with more photos if there's a need or if I am going to do another one.
