How Much Do Science Parties Cost? (2026 Prices)

Typically $215–$375 per event to start, for a one-hour home show (Mad Science of Colorado, Mad Science of the Triangle and Mad Science Bay Area, 2026). Those are other companies' published rates, not Yombu prices; Yombu shows real listed rates here the moment local science party hosts join, and you always see the exact total before you pay.

Usually one flat fee per party, not an hourly clock. Science parties are one flat show fee, but the guest count usually sets the tier — Mad Science of Colorado's one-hour show runs $215 for up to 10 kids and $364 for 21–25. On Yombu, a science party host's flat price is on their profile, and the exact total shows before you pay.

Guest count and take-homes. Science party companies often price in tiers by the number of kids, because every child gets materials and a take-home creation; Mad Science of Colorado's tiers step up at 10, 15, 20 and 25 kids. Add-ons like dry-ice potions, rocket launches or cotton candy, and travel, move a quote too. On Yombu a host's real flat price shows on their profile.

No. The total you see at checkout is the total you pay — and your money is held safely until after the party, so you're never paying upfront and hoping. If an entertainer charges for travel or add-ons, it's itemized before you book.

Not automatically — Yombu prices don't surge. But weekend afternoons are when the most-booked local pros fill up first, so booking a peak Saturday late can leave only higher-rate options. Booking a few weeks ahead, or choosing a weekday or morning slot, keeps the full range open.

You pay online when you book, and your payment is held until after the party. Cancel 7 or more days before the party for a full refund. From 7 days to 48 hours before, you get 50% back and can still reschedule or move indoors free of charge; within 48 hours of the start time, the booking is final.

Usually not in any way that matters. Quote marketplaces add client service fees on top of quotes, and going fully direct means chasing availability by phone and paying by cash or transfer with no protection. On Yombu you see the entertainer's real listed rate, we confirm genuine availability in about two hours, and your payment is protected until the party's done.

If you choose to tip, 10–20% of the booking or $15–$20 per performer is the norm GigSalad's 2026 party-budget guide suggests. Tipping is optional and never added to your Yombu total. Mad Science's own party pages list gratuities of 10% to 20% as typical, so the general norm holds for science shows too.
