Our take
4/5Mad Science sends a presenter to your home or a rented room with a hands-on science show for kids turning 4 to 12. Every in-person party includes slime that each child makes and takes home, and the bigger packages add a rocket launch, dry ice potions, static electricity experiments or cotton candy.
The Standard package costs $295 for up to 15 kids and 45 to 60 minutes; Super runs $360 for 75 to 90 minutes with one add-on, and Mega is $510 with two add-ons and 15 favor bags. Extra children are $8 each. You provide a sturdy table, water and an outlet, and the scientist cleans up. Booking at least three weeks ahead is recommended.
