Parents of littles PSA: Get this bubble mix. It is the best. Use it to beef up the cheap-o stuff at the store or mix it 1:4 with water for super bubbles and keep your kids from getting bored after 0.0005 seconds of their bubbles because they can't blow a decent bubble.
Bonus PSA: Get the individual Fubbles brand no spill bubble cups. No fights over bubble containers.
You're welcome. Enjoy banishing your kids (happily) to the outdoors.
