(Inside: A simple, fun recipe for TARDIS bath bombs—perfect for the Doctor Who fan who adores that iconic blue police box.)
Do you know someone who’s utterly obsessed with the TARDIS and everything Doctor Who?
The TARDIS—“Time and Relative Dimension in Space”—the time machine that travels across time and space might show up on their car mirror, holiday decorations, or jewelry. If that blue British police box makes them smile, these TARDIS bath bombs are an ideal gift.
They’re easy to make and feel delightfully unique—like a little piece of Whovian magic.

You can present them on their own or include them in a gift basket with a few themed extras—earrings, pendants, or a small TARDIS backpack would all pair nicely if you want to build a larger present.

TARDIS Bath Bombs – The Perfect Doctor Who Fan Gift
What You Need:
1 cup baking soda
1 cup citric acid
1/2 cup cornstarch
3 tablespoons coconut oil
3 to 6 drops fragrance oil (or essential oil blend of your choice)
5 drops blue food coloring
blue cake glitter (optional)
bath bomb mold

How to Make Them:
1. In a bowl, combine the baking soda, citric acid, and cornstarch. Stir thoroughly to remove lumps and blend evenly.
2. Add the coconut oil and mix with a fork or whisk until the mixture stays light and fluffy. The oil helps bind the ingredients and add moisture to the bath bombs.
3. Mix in the fragrance oil and blue food coloring, stirring until the color and scent are evenly distributed. Add the coloring a few drops at a time until you reach the desired shade.
4. If you want a little sparkle, sprinkle some blue cake glitter into the mold before packing in the mixture.
5. Pack each side of the bath bomb mold firmly with the mixture, then press the halves together. Hold them pressed for about a minute, then gently remove the formed bath bomb and place it on a tray to dry and harden overnight.
Once fully hardened, your TARDIS bath bombs are ready to gift. They look great stacked in a box or nestled in tissue paper inside a themed gift basket.

These TARDIS bath bombs make a charming, handmade present that any Doctor Who fan will appreciate. They’re simple to craft, customizable in scent and color, and perfect for gifting all year round.
