制作沐浴炸弹的小贴士

Top tips for making bath bombs

Be sure to use liquid food colouring, not gels. Gels will clump together when you add them to the bicarbonate and it's hard to mix them in.

Once you've added the liquid to the mixture, you need to work quickly to mix everything together and push it into the mould as soon as you can.

To allow your bath bombs to dry, leave them uncovered in a cool, dry place (away from taps and humidity). They will take longer to set in humid weather.

If you've got more than one colour, why not make a rainbow bath bomb? Layer up the different colours and they will blend together beautifully.

制作浴弹的小贴士

一定要使用液体食用色素，而不是凝胶。当你把凝胶加入碳酸氢盐中时，它们会结块，很难混合进去。

一旦你向混合物中加入了液体，你需要快速地把所有东西混合在一起，并尽快把它推到模具中。

为了让你的沐浴炸弹变干，把它们放在一个凉爽干燥的地方(远离水龙头和潮湿的地方)。在潮湿的天气里，它们要花更长的时间才能凝结。

如果你有不止一种颜色，为什么不做一个彩虹浴弹呢?把不同的颜色层叠起来，它们就会完美地融合在一起。
