Good thing to do
Making little friends.

Keep Daphnia or some other little crustacea, they may not be the biggest class pets but they are fascinating.
You can use material from a pond, or get a bag of live fish food from a pet shop and save them.
I have also kept Sea Monkeys which seem to be the same thing as brine shrimp (Artemia sp.) and they are great.
The crucial thing seems to be that they need salt water and occasional feeding.
Triops are fantastic but trickier, mind you, you do get the fun of seeing if they eat each other.
Apparently they are all happy with small amounts of fish pellets or dried yeast.
Using a wide container will keep them oxygenated and changing the water occasionally will help with waste build up.
Or if you are using Daphnia you could let one lot go and get some more.
Health and safety. The water from all these should not be drunk. Wash hands after handling.
If you have any old lab kit to get rid of please let me know, I might be able to use it.
