Last-minute curiosities

Got questions?

Most folks ask the same things. If yours isn't here, we're a DM away.

Chat with the bar →
Are the drinks alcoholic?

Nope — everything we serve is 100% sober. Dirty sodas are layered sparkling sodas with flavored creamers and snack toppers. Our mocktail bar is grown-up presentation, zero proof.

What about allergies?

Each station lists allergens up front. Slime is non-toxic, paint is washable acrylic, drink creamers come in dairy and oat. Tell us at booking and we'll plan around it.

Is the studio messy? Should we dress for it?

Yes and yes — that's the point. We provide aprons; we recommend leaving white tees at home. Tie-dye stations include a fresh tee.

Where do you host, and do you travel?

Home base is Charlotte, NC. For parties of 12+ we travel anywhere within 90 minutes; further than that, ask us.

Shipping & returns on kits?

Kits ship in 2-3 business days, free over $50. Unused kits are returnable within 30 days; opened kits aren't, for hygiene reasons.

Meet the bar

Hi, I'm Mr. Barr.

I built the lab because birthday parties got boring and bar nights weren't for everyone. So I made a place where you can pour a drink, make a mess, and walk out with something you actually made.

What started as a pop-up soda cart in 2021 is now a six-station studio in Charlotte and a kit business that ships nationwide. We're sober-friendly, kid-friendly, mess-friendly, and very, very pink.

Birthday Buyout · 24 guests

My daughter still talks about it three weeks later. Six stations, a soda bar, the whole lab to ourselves — and somehow none of the parents wanted to leave either. Mr. Barr is a literal magician with kids and glitter.

Mocktail Mixology

Took my whole girls' trip here instead of a bar crawl and it was the best call we've ever made. Sober-friendly fun that doesn't feel like a compromise.

Slime Lab

My 8yo declared this the greatest day of her life. The cleanup-included thing? Worth every penny. We've booked twice more.

Paint-Pour Bears

I came in skeptical and left with a tie-dyed bear named Steve, three new flavor opinions, and a 4-pack of peach-ring soda. 10/10, no notes.

Dirty Soda Kit

Ordered the build-your-own kit for a road trip and our kids would not stop talking about it. Knocked off one star only because I wanted MORE peach rings.

Corporate Mixer

Booked the lab for a 30-person team off-site. Even our most introverted engineer was tie-dyeing socks by the end. Best team-building money we've spent.
