Why drinks tip on a concert lawn
Separate a narrow footprint from a sloped surface, moving blanket or passing foot. Those problems need different solutions.
A wider base changes the footprint
Steadi grips compatible drinkware with flexible fins and widens the support footprint. The intended setup still needs a level, fully supported base. No numerical spill-reduction result or tested slope rating is claimed.
A hill remains a hill
A container on a slope can remain tilted even with a wider base. Steadi does not self-level or fasten to the ground. If the base rocks, leans or is partly unsupported, relocate the drink or choose a suitable permitted alternative.
A moving blanket changes the surface
Pulling a blanket, sitting on a fold or moving a cooler can shift the drink’s support. Keep the drink clear of those actions and pick it up first. A broad base is not a substitute for checking what moves beneath it.
Spills do not always come from tipping
An open cup can splash without falling. A foot can kick a drink regardless of its base. Steadi is not a sealed lid or crowd barrier. Placement, permitted lidded drinkware and moving the drink when people stand address different parts of the problem.
Make a better choice for your spot
If you have a level, supported place within reach, Steadi may be a useful wider base. If you need elevation or attachment, compare a permitted chair holder or table. Use the options guide, then check the exact container before buying.
