Bubbles. Circus. Fun.

Bubbles are enchanting, just like your vision for your party 

Do You Also Do Indoor Parties?

Big Top Bubbles offer both indoor and outdoor bubble services.


We do a shorter stage show in indoor events, that features kids in bubbles - where we actually put audience members into a huge bubble after a short demonstration that is fun, impressive, and even educational.


Enjoy a longer celebration of bubble arts, in a party that includes multiple soap bubble experiences and tools. I come fully contained, you don't have to worry about anything. The satisfaction from playing with the bubbles is epic. Often, kids and their parents will explore the bubbles together and bond over an experience they will never forget.

Holiday Parties

When you book Big Top Bubbles as your entertainment provider for Spring Events or any holiday event, you get to spoil your guests with a unique, fun, safe, and memorable experience. Everybody loves the photos that they can take with the big bubbles, and we can even incorporate some holiday spirit in the event with games, a mini show or even roaming entertainment.

Each huge bubble feels like an Easter Bunny moment.

We had Hernan perform at my son’s 3-years old birthday party and the kids loved him. He came to the party before the starting time, fully prepared and started engaging the kids from the start. Both kids and adults were extremely impressed by the giant gaint bubbles, running after them and trying to pop them. Hernan had all the kids following him around, making them laugh with his clowning skills. Bubble theater is a unique and new entertainment and I definitely recommend it and Hernan to wow your guests. It also makes beautiful pictures!
Hadas T.
He is great with kids and he even impressed the adults. Besides the cool bubbles he also did comedy which was icing on the cake. The kids laughed for the whole 90 minutes and played with tons of bubbles. Hernan is very professional and came right on time. I would love to hire him again.
Himani A.
Hernan was the highlight of my daughter's fourth birthday party at Presidio Wall playground. He has a calm demeanor and entertained the ~20 children (and parents) without taking over the party, making them laugh, delighting them with bubbles of all kinds, and staying late to keep the party going and entertain the birthday girl.

Everything to Know About Bubbles for Your Big Day!

Weekends, especially in the spring and summer, often book 3-6 months in advance. If we are already booked on your requested date, we can talk about other options (including booking later in the day). Reserve your date today!
We take cash or check for the full amount, on the day of your performance.
Tips are gratefully accepted but never required.

For kids’ birthday parties, we like to start bubbling right at the party’s start time, so kids arrive and can jump right into an activity. 60 minutes of bubble fun gets everyone to the perfect place for singing happy birthday and having cake.
We’re happy to work with you to design the perfect bubble experience for any event. Give us some details about what you have in mind and let’s talk about it!

My new indoor bubble show is the right solution for indoors. I am also accomplished in several circus arts, including magic and juggling.
We custom-make all of the juice for your event.
Anything can be harmful to grass in large enough amounts, but we take care to use non-toxic ingredients. More importantly, to absolutely minimize the amount of solution that enters the soil, run your sprinklers the night before the event and right after the event is over, and you will be fine.
I make a variety of bubbles, from super giants to big masses of smaller bubbles—I might even show you some fun foams! The kind of bubbles I make for your show will depend on my bubble partners: the wind, sun, and humidity. For giant bubbles, the best conditions are very humid, with just a slight wind and cool conditions. My bubble performances are always tuned to the conditions and landscape we are in!
We custom-make all of our bubble equipment, and some of it is very large and requires some practice to use. If you’d like to make bubbles yourself, be sure to ask us about “Bubble Stations”—we’ll bring everything so that all of your guests can make some spectacular bubbles with user-friendly bubble wands.
