Berry Bath Blend (Body Shop) Where do the bubbles stay?

Like other products from The Bodyshop, this smells like the packaging promises. A sweet scent of berries. I bought this as a nice extra for the kids in the bath. It costs 8 euros for 1 bottle of 250 ml. In the store, I asked how much to use. They said a good shoot. On the packaging, I read 1/4 of the bottle. Then you can only use this product 4 times. Which amounts to 2 euro per bath. My experience: I use a good shoot because I want to be able to use it more than 4 times and because I never really put a lot of water in the bath. The bath turns pretty pink, but I miss the bubbles. There are some bubbles, but they disappear as fast as they come. Especially when they come into contact with soap (by washing the children), they melt away almost immediately. At this price, I had higher expectations. The scent is nice and the kids like a pink bath too. But I bought it mainly for the bubbles anyway.
