Introduction: Condom Ecosphere

Create the circle of life... in a condom! This ecosphere, similar to ones developed by NASA, will last a reasonable amount of time if left in indirect sunlight during the day. Very fun and maintenance free. Fishtank and focal point of desk!

EDIT: DO NOT ATTEMPT! POSSIBLY DANGEROUS FOR ANIMALS!

Click play to watch. Thanks all, took a lot of work.


Step 1: Watch Video.


Start off by opening and cleaning condom with water. The thinner the condom, the more easy to see through, but the weaker.

Step 2: Pour Gravel, Plants, and Snails

Pour your gravel, your plants, and your snails into the condom wit water. Use a funnel or make one out of a bottle (as shown in video). Be gentle as this is when you are most likely to pop the condom.

Step 3: Add Fish

Add your fish. I like to use neon tetras because they are small and won't eat the adult snails.
Make sure to hold the lip of the condom, as it will want to lose grip as it fills with water.

Step 4: Tie Knot

Now tie a knot in your condom, like always when finished!

C O N G R A T U L A T I O N S!

What a realization, so why don´t you just delete this stupid idea!!?!?!

hahah now when the fish dies from pure lack of oxygen you can flush them both down the toilet... i could suggest putting sea monkeys into the condom... but it seems most of us already do... honestly, i put potatos in theis things cause they have a better seal around them when they fly out of the potato cannon! im serious!

thats sad. but it says that the plant produces oxygen. still wondering about the food though, does it eat the plant? hmmm...

i feel unconforble im goung to leave

hang the condom with the top open and feed through it

hahaha I'm studying to be a high school bio teacher and I think I just got an idea for a project. :P
