How do I make a roof pop off?

How do I make a roof pop off so I can see the interior. I'm making a moc that has 3 floors I want to be able to pop each segment off so I can see the interior of each floor, how does one do it?

What’s in the box

I’m trying to get this box of Lego, what do you guys think is in it? I know it’s a “starwars” set and an other. TIA

The Fearsome Foes of Spider-Man expand their ranks!

Thought this could make a cool gernade, thoughts?

It's one of those levers with the lever part taken out and put on a 1x1 round brick

GWP when I got Concorde today. Preview copy of the Cat set!

Finished after 4 years

I bought this set 4 years back, but all the pieces came in 1 bag, which melted my little brain. Was able to mostly finish it, just missing a few pieces and all minifigs (except a part of Warrior Kitty and Lucy's weapons) It's been through 2 moves, 3 houses. Hoping to add them to my LEGO City soon, maybe even find the minifigs if I'm lucky!

Lego Mario minifigures I made

Due to a recent "financial decision" I am in a surplus of pink LEGO frogs. What should I do with them?

Does anyone know this part number?

I’m considering these for a minifig display, but need a lot more. My wife bought some unofficial displays with studs that feel too large for minifig legs. Has anyone used them for minifigs successfully?

Made a 6x6 Gladiator out of two Jeep sets (42122)

My son got two Jeep Rubicon sets for his birthday by accident. Instead of returning one, he said he wanted a 6x6 truck like he has in Snow Runner. Been a while since I’ve custom made a LEGO build but we had a fun time working on it together and I’m really happy with the result. Even all wheels have working suspension!
