Teach Soap

I made a batch of bath bombs yesterday with very basic recipe:
200g baking soda
100g acid citric
1 tbsp of grapeseed oil
The oil is added after blending the first two well. Then while whisking I added 2-3 spritz of rose lotion. The mix turned out clumpy(some tiny balls in the dough) but could be molded easily.
When I took them out of the molds, after a few minutes I saw they started frizzing. That scared me so I immediately wrapped them in plastic bags and left them in my room (AC = 26oC). After about 1 or 2 hours, I saw lots of water bubbles around the bags and the bath bomb's surface got some tiny holes. I think maybe I put in too much water or my room is too humid? I checked some weather forecast website and found that my city has 100% humidity.

Today I tried 1 of my just made bath bomb, but it was a failure. WHen I dropped it into my tub, it sunk right to the bottom and broke into dusts with little frizzes.
Please give me some advices.

Yes, the high humidity can cause problems. Also, if there was water in the rose lotion you sprayed with - which there most likely was - it may have made the mixture too wet. When that happens, the chemical reaction takes off on its own.

Is there a drier area you can work when you're mixing these?

My rose lotion has water in it. So maybe I spritzed too much water.
A drier location? It should be 500km away from here j/k.
I will try my kitchen. Here the rain season is leaving so I just have to wait I think.
