stinky jelly soap (vegan or meaty) yay ridiculousness. This stuff also removes smells from the hands really well.

You will need a saucepan.
and
1 tsp salt (to prevent mold on your agar soap)
also
1 oz solid oil melted (like coconut, cocoa or shea) or lotion (optional but strongly suggested)
If you want to use solid soap boil these together until mushy ( half cup of grated solid castille and 1/4 cup water) along with your melting solid oil ( and then skip the liquid later)
1/2 cup almond milk (or another 1/2 c of water if you don't want pastel colored items)
1 pkg no sugar included veg or non veg gelatin (flavoured or not as you desire, flavoured will contain citric acid which is rough on dry skin)
1 cup boiling water
optional 1-2 tb glycerin (which also tends to make the gel a bit shimmery and emoliating)
optional: 2 tb exfoliants like lavender flowers, poppyseeds, almond meal, ground oats, citrus peels, almond milk shredd, almond meal,rice meal,etc...
Using a whisk ,mix until almost stringy as with jello. Try not to allow foaming.
add 2-3 drops of food coloring and 5-10 drops essential oil or scents of choice per your whim and/or skin sensitivity(less is frequently more...if it burns on your wrist it hurts more elsewhere)...this time I used sandalwood and lavendar with the lemon jel and almond extract with the strawberry jel.
remove from heat
stir in:
3/4 cup non petrol liquid soap (castille, soap nut liquid or dish soap types are cool) if you didn't use the solid soap option)
1 shot glass (1 oz) of vodka or vinegar (if you have dry skin avoid the vinegar as it is drying)
pour into heat resistant jar or small rigid molds (cupcake, soap or candy molds work well). chill and rest in fridge at least 2 hours before use.

 Keep in airtight container and label well. If your container is glass make sure it doesn't break. It looks and smells like candy...so don't let little kids use it unless they understand eating soap is bad and that this is soap.
Use as shower gel or shampoo. (rinse extra if you used agar as it doesn't dissolve at room temp like carageenan or animal gelatin) feels nice chilled or frozen sometimes. If you used almond milk please refrigerate. Lasts up to 2 weeks at room temp, 2 months frozen. you can also submerge funky trinkets of food safe plastic in the soap for decorative purposes.
