In Delaware, you don't need a licence to own a shotgun.
You don't need a permit to buy a shotgun or carry a shotgun.
If you're over 18, and you pass the background check, the state won't interfere with your shotgun.
Sparklers, however, are a different matter.
Guns v Sparklers
"A person has the right to keep and bear arms for the defense of self, family, home and state" (Delaware constitution, article 1, section 20)
"No person shall store, sell, offer or expose for sale, or have in possession...any fireworks" (Delaware code, title 16, section 6901)
Unless you have a permit for a public display, it is illegal to sell or possess fireworks in Delaware.
That includes sparklers - which the law specifically mentions.
The maximum fine is $100. Last year, 17 people were arrested in Delaware for fireworks offences.
While the US constitution does uphold the right to bear arms, it doesn't uphold the right to bear roman candles.
In the US, firework laws vary from state to state, even town to town. Like Delaware, Massachusetts bans all consumer fireworks - including sparklers.
Illinois, Ohio, and Vermont ban everything but sparklers and novelty items. Other states ban anything that flies.
The laws mean firework stores are often found on state lines, so customers from one state can take advantage of laws in another.
Patriotic Fireworks is in Elkton, Maryland - six miles from the Delaware state line. It's a small, friendly store, found down a long, tree-lined track.
A pig-tailed dog called Princess Sofia says hello to customers. A sign on the door says: "Let freedom ring".
But they take the law seriously.
Firstly, they don't sell to people from Maryland. They could, but the state law is so complex, and so strict, it's not worth their time.
"I would have to dedicate a person to go round with each customer, to make sure they bought legal items," says owner April Frederici. "It's just easier not to."
They do sell to Delaware residents - "I can't be the world's policeman," says April - but every customer must sign a contract.
It states that fireworks will be used "in accordance with all state and local laws". It also says Patriotic will not be liable for any "accident or injury".
And when it comes to fireworks, accidents do happen. Just ask American football player Jason Pierre-Paul.
