Dunk tanks are one of the most effective fundraising attractions because they are simple, interactive, and entertaining. When done right, a single dunk tank can raise hundreds—or even thousands—of dollars in one event.This report outlines proven strategies to maximize fundraising results.
1. Choose the Right “Dunker”
The person sitting above the water matters more than the tank itself.
High-impact choices:
- School principals or teachers
- Local business owners
- Coaches
- Popular coworkers or managers
- Friendly rivals (boss vs. employee)
- Town Mayor
- Chief of Police
Tip: The more recognizable the person, the more people will pay to dunk them.
2. Set Simple, Clear Pricing
Keep pricing easy to understand and encourage repeat throws.
Popular pricing models:
- $1 per throw
- $3 for 3 throws
- $5 for 6 throws
- $10 “VIP” package (priority throws or guaranteed dunk)
Bonus idea: Offer a “Guaranteed Dunk” ticket at a premium price.
3. Create a Schedule (Rotation Builds Crowds)
- Rotate dunk tank volunteers every 20–30 minutes.
- Why it works:
- Keeps energy high
- Gives people a reason to stay
- Encourages repeat donations to dunk different people
Post the schedule clearly so attendees know when their favorite target is up.
4. Use Challenges & Competitions
Turn dunking into a game.
Here's how to use your dunk tank rental as a game:
- “Beat the Boss” hour
- Team vs. team dunk totals
- Departments, classes, or clubs competing
- Reward the highest fundraiser with a prize
Example:
“Whichever teacher raises the most money gets the day off from car duty.”
5. Add Visual Motivation
- People donate more when they can see progress.
Effective tools:
- Dry-erase board tracking money raised
- Thermometer poster showing fundraising goals
- Bell or horn every time someone gets dunked
- Loud reactions attract crowds—and crowds attract money.
6. Accept Multiple Payment Options
- If possible, offer:
- Cash
- Venmo / Cash App / Zelle
- QR code payment signs
Removing payment friction increases impulse donations.
7. Upsell & Bundle
Increase revenue without adding effort.
Upsell ideas:
- Sell foam balls or extra throws
- Bundle dunk tank with concessions
- “Fast pass” to skip the line
- Group discounts for friends
8. Promote Before the Event
- Fundraising starts before the dunk tank is set up.
Promotion ideas:
- Social media posts announcing who’s getting dunked
- Flyers with photos of volunteers
- Email or text blasts
- Countdown posts (“Principal Smith gets dunked Friday!”)
- Pre-event hype dramatically boosts turnout.
9. Safety & Cleanliness Matter
A clean, safe dunk tank encourages participation.
Best practices:
- Fresh water
- Non-slip area
- Clear throwing line
- Staff supervision at all times
When people feel safe, they’re more willing to join in.
10. Thank Donors Publicly
Recognition increases generosity.
Examples:
- Shout-outs over a microphone
- Social media thank-you posts
- Signs recognizing sponsors
- Small prizes for big donors
People love being acknowledged.
