I know this post is a little old, but if you're still looking for some info I will shed some light, and maybe someone else who is interested will find this helpful.

You are entering into a very fun and addicting world. I wouldn't quite desribe pouring plastics as 'easy' but it's definately not rocket science.

For what you have mentioned, you won't need hardner or much plastic additives. For a basic set-up and to create baits for personal use you will NEED the following:

Plastic Supplies:
Medium plastic
Colors
Salt
Glitter (optional)
Scent (optional)
Pyrex cup
Microwave
No hardner or anything is needed for the standard baits you listed. Medium plastic with some salt will give you a great consistency.

Now for molds.. Aluminum molds are extremely expensive. If you have your heart set on them, I would recommend one-piece molds if you are on a budget. They are half the price, and will be flat on one side, but will be fine for personal use. They take a little more skill to pour, but nothing you can't get the hang of.

Definately have to have a work shop. There you will need a microwave, large working table, etc. Also, keep in mind that ventilation is also something that is needed.

Once you start pouring you will get the hang of the temps and consistency the plastic needs to be when it's ready to pour. If you don't add any colorant or anything until plastic is hot, the plastic will turn totally clear, and fine bubbles at the top when it is ready. Then you can add your colors, salt, and glitter.

Now the fun part... Experiment! Try new colors, swirls, and two colored worms.

Good luck on everyones quest. If anyone has any questions, feel free to PM me and I will be happy to help someone along.
