We recently bought one bag of each color ( blue and pink ) for our gender reveal . It worked perfect ! We did a test trial of each color ( 2 tbl spoons in each exhaust , it was good but decided to use more the day of the reveal so it would be a little brighter . It ended up being blue and we were all so excited !! We did half the bag in one side of the exhaust and the other half of the bag in the other and it turned out perfect !! We revved the engine and the powder came out right away ! We loved this product and Would suggest using this brand over any others!
