1/2 c Dawn
2 c water
2 tsp sugar
Combine and boom! you're done. So far it's worked great and keeps easy in a mason jar in the closet.
And works in every bubble thing we own: big bubble wands, little bubble wands, and bubble guns. Except the big Fubbles pot we bought, it's just as annoying with this as anything else. Don't waste your money! Bite the bullet, be a lazy mom and buy a decent bubble gun. Your lungs will thank you!
Also:
Just don't do it. That sucker gave us two bubbles and was done. I knew better. I had read reviews, but fell into the "but it's so cute" and "surely a Fisher-Price thing would work" traps. Trust me, it's crap, don't buy it!
Spend that money on a bubble bazooka! :-)
