Make sure your honoree is kept busy for a few hours to ensure the element of surprise. A short errand might not give you enough time, in which case you will have to speed up or rush the process.

You will be able to retain the element of surprise by organizing the party around the guest’s typical schedule.
Choosing a public venue usually means you have less time to easily attend to details, because space is often rented shortly before your event, giving you less time to decorate and prepare. When choosing a location, make sure it is easily accessible to your guests.
Talk about their birthday as easily and calmly as possible. This will keep them from becoming suspicious or thinking that everyone has forgotten about their birthday.
Consider your honoree’s reaction before taking this route. Some people will not be happy about getting their clothes wet or having their hair covered with silly string.
