How Can I Prepare Those Dolce-Gusto Coffee Thingies/Capsules without Those Devices?

-I know nothing of coffee. I just bought some weird stuff from a hypermarket and it seemingly can't be made like normal boiled or instant coffee...

I do not drink enough fancy coffee for those devices to be worth the money. I just don't. I'm a tea drinker. They cost much more than the price of all the damn coffee my family would drink in one year. My parents have no clue what Latte Macchiato is, seriously.

So, please, tell me, should I just throw the damn capsules or is there some way to prepare it by simply or more complicatedly boiling it?buy a cheap coffee maker
